BGP routing issue

Unanswered Question
Nov 12th, 2007


I'm having a problem with a new network i've added to my router. I've added a network and and have added the following SubInterface config for one of them:

interface FastEthernet0/0.5

description Voice Vlan

encapsulation dot1Q 5

ip address

no ip redirects

ip pim sparse-dense-mode

ip cgmp

no snmp trap link-status

standby 1 ip

standby 1 priority 105

standby 1 preempt

standby 1 track Serial0/1/0:0

I've added it to my BGP AS as below:

router bgp 65202

no synchronization

bgp log-neighbor-changes

network mask

network mask

network mask

network mask

network mask

network mask

aggregate-address summary-only

also I've added the following ACL:

access-list 108 deny udp host any eq 5000

access-list 108 permit ip any

access-list 109 permit udp host any eq 5000

But I can't acecss this network from another other router. Any idea what i'm missing. i'm not an expert on Routing.

If you do a show ip bgp in the neighboring router, can you see the new prefixes? Also, just to check, when you do show ip bgp summary, can you see the neighbors you are expecting?

In the neighboring routers, what do you get for show ip route

Hi Kevin,

I see this when i do a show ip bgp:

*> 0 32768 i

s> 0 32768 i

* i172.17.10.0/23 0 100 0 i

*> 32768 i

s> 0 32768 i

* i172.17.19.0/27 0 100 0 i

*> 0 32768 i

* i172.17.19.32/27 0 100 0 i

the neighbors seem normal. I've checked the same setup on another router in a different location,...these are and it shows up as follows:

s> 0 32768 i

s> 0 32768 i

s> 0 32768 i

s> 0 32768 i

s> 0 32768 i

Could it be to do with the way I have HSRP set up?

HI, [Do Rate if HELPS]

You should have missed the I-BGP routing:

What is the IGRP protocol you are using ?

Pls check was there any "ip route" command need to be added for internal route synchronization. Like,

ip route

Do Rate if HELPS
