Redundancy Configuration in CISCO Router

Dear All,

Hello! I'm running a ISP. I have a CISCO 7204 Router. I take bandwidth from an IIG. They provide me two peering IP block (main and backup) and I configure BGP in router with one of them (main link). Config sample is given below:

------------------------------------------------------------------------

interface GigabitEthernet0/1

 description IIG-Backup

 ip address 43.245.140.162 255.255.255.252

 duplex auto

 speed auto

 media-type rj45

 no negotiation auto

!

interface GigabitEthernet0/2

 description IIG-main

 ip address 103.15.245.2 255.255.255.252

 duplex auto

 speed auto

 media-type rj45

 no negotiation auto

............................................

router bgp 38192

 no synchronization

 bgp log-neighbor-changes

 network 43.245.244.0 mask 255.255.252.0

 network 43.245.244.0 mask 255.255.255.0

 network 43.245.245.0 mask 255.255.255.0

 network 43.245.246.0

 network 43.245.246.0 mask 255.255.255.0

 network 43.245.247.0

 network 43.245.247.0 mask 255.255.255.0

 neighbor 103.15.245.1 remote-as 58717

 neighbor 103.15.245.1 description "eBGP With IIG"

 neighbor 103.15.245.1 soft-reconfiguration inbound

 neighbor 103.15.245.1 prefix-list IIG-in in

 neighbor 103.15.245.1 prefix-list IIG-out out

 no auto-summary

!

ip default-gateway 103.15.245.1

So you guys understand that my primary IIG link configured in Gb0/2 interface and I also done BGP. My IIG given me another peering IP in Gb0/1 to use as redundant. So that if primary link goes down, secondary link UP automatically and all internet traffic goes through this. But How can I configure another BGP for secondary link? How to configure Gb0/1 as auto redundant link? So that If Gb0/2 goes down (Fiber cut or any reason) then I can get internet using Gb0/1 (secondary link) automatically.

Can anybody help me here? Thanks.

Often that's a simple as configuring another neighbor <new IP> remote-as #.

You may also need to have similar bgp neighbor statements, for the new IP, like you do for your existing neighbor.
