861Router

Question:

i have a new 861 router no cisco price wireless or anything and i am having trouble gettting it to work. i put the IP address on the Fastethernet 4 and the inside ip address on the VLAN1 i can ping out from the router both ways to the gateway and back to the local machine but i can not get out to the internet from the local machines.the DHCP works just cant get to the internet

below is a copy of current config any help would be great.

Answer:

As mentioned you need to configure NAT properly.

Something like:

interface fa0/4

ip nat outside

interface vlan1

ip nat inside

ip nat inside source list 4 interface fa0/4 overload

And remove this line - you don't need it:

ip route 192.168.4.0 255.255.255.0 10.5.10.1

I am curious as to what else you have upstream of this router - you are natting from one private range to another so there will need to be something further upstream that can NAT this traffic Catalyst Switches Price to a routable address.

Issue with floating static route

Question:

 am having issues with my WS-C3560X-48T-L  floating static route - this must be something easy but I am not "seeing" it today... :-)

I have a few hundred prefixes from the 10.0.0.0/12 range in my BGP table and I want to be able to advertise another range (192.168.1.0/27) when any element of the 10.0.0.0/12 aggregate is present in the routing table. Example: If 10.1.1.1/32 is present, then advertise 192.168.1.0/27. My current problem is that the floating static doesn't kick in, even when the locally originated aggregate is present. Looks like the floating static doesn't like following another static route that is pointing to Null0 (which gets dynamically originated by the aggregate). Currently the floating static only kicks in when a prefix is present in the routing table that has zeros in all of the last three octets, i.e. 10.0.0.0/12 , 10.0.0.0/16 , 10.0.0.0/32

Any solutions / ideas to get around this?

CE1#sh ip route 10.0.0.0 255.240.0.0

Routing entry for 10.0.0.0/12

  Known via "bgp 65000", distance 200, metric 0, type locally generated

  Routing Descriptor Blocks:

  * directly connected, via Null0

Answer:

Try changing the next hop address for your static route as follow:

ip route 192.168.1.0 255.255.255.224 10.0.0.1

10.0.0.1 should always be resolvable via the aggregate route (10.0.0.0/12), which should always be present WS-C3560X-48T-S Price in the RIB as long as there is a more specific route in the RIB.

VPN UP-ACTIVE but cannot ping across VPN

Question:

I have a VPN setup that cisco price I am trying to get workling.  When I issue the command sh crypto session on both routers I get the following:

OFFICE:

Interface: FastEthernet0/0

Session status: UP-ACTIVE   

Peer: 70.193.192.131 port 14275

  IKEv1 SA: local 40.197.68.9/4500 remote 70.193.192.131/14275 Active

  IPSEC FLOW: permit ip 192.168.10.0/255.255.255.0 192.168.30.0/255.255.255.252

        Active SAs: 2, origin: dynamic crypto map

HOME:

Interface: GigabitEthernet0/0

Session status: UP-ACTIVE   

Peer: 40.197.68.9 port 4500

  IKEv1 SA: local 192.168.30.1/4500 remote 40.197.68.9/4500 Active

  IPSEC FLOW: permit ip 192.168.30.0/255.255.255.252 192.168.10.0/255.255.255.0

        Active SAs: 2, origin: crypto map

But when I issue a ping 192.168.10.1 from the home router it returns .....

Here is my network topology:

Attached are my config files.

First, I do not know what I need to do to get the home router to ping the office router.  Secind, what do I do to get the 192.168.2.0 network (phone) to cross the VPN all the way to my phone.

Any help you can provide, I will be greatly thankful for!!!

Answer:

Looking at your config, you're doing NAT per ACL 1, on your OFFICE router, for source of 192.168.10.0/24.  You're NATing your OFFICE LAN to your public interface BEFORE it's being sent through tunnel:

http://www.techrepublic.com/article/understand-the-order-of-operations-for-cisco-ios/6055946 (NAT Order of Operations)

Change it to an extended and insert a line to that to deny NAT for your HOME network destinations across the tunnel:

ip access-list extended SDM_ACL

deny   ip 192.168.10.0 0.0.0.255 192.168.30.0 0.0.0.3

permit ip 192.168.10.0 0.0.0.255 any

That will take care of connectivity to the /30 subnet, but if you're wanting access to the OFFICE from your 110 and 115 VLANs from your HOME, then you'll need to add those networks to Catalyst Switches Price the VPN1-FLA-TRAFFIC and VPN-TRAFFIC ACL's, respectively.

Cisco 887VA M K9 on domestic (dynamic IP) BT ADSL

Question:

IDoes anyone have a working WS-C3750X-12S-S Price config for this setup, I configured using the BT instructions but still no internet, I have tried various solutions from the forums but still no internet or ability to ping outside networks. I have in vain tried to get the latest BT firmware for the router but no joy so far.

Answer:

Okay then just change the dhcp pool to have your isp dns server address in###########stead of  your ##router then you should be good to go.

You can remove the two virgin WS-C3750V2-48PS-S dns server address also is you wish.

static route definition

Question:

what is the difference WS-C3750X-48P-L between those static routes :

ip route 150.0.0.0 255.255.255.0 150.0.1.1

ip route 150.0.0.0 255.255.255.192 150.0.1.1

Answer:

ip route 150.0.0.0 255.255.255.0 150.0.1.1

#means route anything matching 150.0.0.x to 150.0.1.1

ip route 150.0.0.0 255.255.255.192 150.0.1.1

#mean route anything matching WS-C3750X-48PF-L Price from 150.0.0.1 to 150.0.0.64 to 150.0.1.1

Outbound Traffic Manage via eBGP

Question:

We are using multihomed eBGP Cisco 3560X  in single Router from multiple ISPs bandwidth for internet.

We have our own IP Address , at present our oubound traffic going throug ISP 1 , when ISP-1 b/w goes down then it will autometic traffic going throug ISP-2 bydefault.

But our required when ISP-1 B/W goes down our all outbound traffic will going throug ISP-3 inplace of ISP-2.

How can i achieve this as per our requirement.

Answer:

Another option is to specify weight - with again giving  the higher vaule to the most preferred path.

Local pref on a single router is a possibility but as I understand it, It would usually be best utilised with ibgp peering-res

ust to clarify - do you mean when the link on ISP1 goes down? It is just that you said "when ISP-1 b/w goes down" which could be interpreted differently.

It would be helpful if you could share your existing configs but the solution that springs to mind is to use local preference on the BGP learned routes with ISP1 routes having a higher local preference than ISP3.

Yes - that will do it. Ignore my comments about Local Preference - for some reason I thought you had 3 routers on site which is why I recommended LP. Weight is a better option if you have a single router.

You can do the configuration as you have written above or write a route-map statement to apply weight Catalyst 3560 Price to the routes learned from each peer.

OSPF path selection ??

Question:

I have the below topology Catalyst 3560 Price in my network I am planing to configure ospf in my network .
Can any one confirm that how traffic will flow from B router to reach the networks behind the a router .
with default ospf configurations .

will it take the directly connected link to reach the router A 's network network ? or will it go through router C to reach the router A ?

Answer:

If you have default OSPF configuration. It will do load balance.

Cost of link connecting Router-A and Router-B = 10^8/1mb = 100
Cost of link connecting Router-B and Router-C = 10^8/2mb = 50
Cost of link connecting Router-C and Router-A = 10^8/2mb = 50

So router B is having two equal Catalyst 3560V2 Price cost path to reach A.
