Cisco BGP Routing Issue

Hi Experts,

 

The issue I have is the inabilitiy to ping ip address 41.40.75.244 on router callkey_pc2 from router CallKey_EGH even though I have route to the ip address in the routing table of CallKey_EGH, as shown

 

Callkey_EGH#show ip bgp

BGP table version is 22, local router ID is 79.99.198.36

Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,

r RIB-failure, S Stale

Origin codes: i - IGP, e - EGP, ? - incomplete

 

Network Next Hop Metric LocPrf Weight Path

*> 0.0.0.0 79.99.198.34 0 44356 i

*> 10.10.10.0/24 79.99.198.34 0 44356 6453 ?

*> 41.75.40.0/21 0.0.0.0 0 32768 i

*> 41.75.47.244/32 79.99.198.34 0 44356 6453 ?

 

I have attached the show run of the routers that may help you to help me. The switches inbetween the routers are flat ethernet_switches (don't have ip addresses)

 

Cheers

Cisco BGP Routing Issue

Hi,

Here I didn't suggest anything but explained why it is not working. you should source the ping from a network than the remote router knows how to get to via TATA.

Regards.

Hi,

To ping the remote prefix from EGH you source from 79.99.198.36 255.255.255.248 so from subnet 79.99.198.32/29

but on PC2 the only match in the routing table is the default route which points out f0/1 which is not connected to TATA and so the replies go out in the wild.

Hi Alain,

Thanks for responding. However, I don't really understand what you're suggesting?

Hi,

add a loopback address and get it into bgp so finally it get advertised to PC2 and source the traffic from there.

Regards.

Alain.
