Solved: Re: BGP ROUTE INJECTED IN GLOBAL TABLE BUT REMOTE ROUTE UNREACHABLE - Page 2

Isaac001 · ‎06-27-2024

Dear Community,

I have I lab setup as attached where R10-R3-R4-R5-R6-R11

BGP routes for R6 routes appear in the routing table of R3 and vice-versa. R5 does the route redistribution between BGP 65200 and EIGRP 100 and vice versa. However, when I try to ping the route at R6 from R3 I can't reach that destination the reverse is also true,why?

I read somewhere that "BGP routers do not
have to be in the data plane (path) to exchange prefixes, but all routers in the data path need
to know all the routes that will be forwarded through them."

So I expected this lab to work but something is wrong, kingly review experts!

Regards,

Isaac.

let me lab it
give me 30-60 min

MHM Cisco World · ‎06-27-2024

Only one thing I see make bgp not work'

In R5 you disable bgp default ipv4 unicast

And then config addresses family but you dont neighbor remote as under it ??

When you disable bgp default ipv4 unicast you can not add any neighbor except under address family.

Maybe that case you face.

Anyway I run lab and share result with you.

Apologies, I made an error on the tunnel source interface configuration, it should have been g0/0 instead of g0/1 on R3 as tunnel source!

The bgp adjacencies have come up! and I can see all the routes in the routing tables.

However, I still can't ping 192.168.6.6 from R3 and 192.168.3.3 from R6.

Also why did we have to use GRE or MPLS to make this work? "BGP routers do not
have to be in the data plane (path) to exchange prefixes, but all routers in the data path need
to know all the routes that will be forwarded through them"-From some book

Thanks for your patience!

not yet, from R5 I can ping 192.168.6.6 and 192.168.3.3 but from 192.168.3.3 can't reach 192.168.6.6. I have shared the configs in my previous post. Thanks for your patience.

MHM Cisco World · ‎06-28-2024

Yes I see but you dont specify source in ping

You need to specify source in ping and it must be ip known by R6 and for that use tunnel IP

Correct! I can now reach 192.168.6.6 from 192.168.3.3 with source pinging!
