BGP help

Hi All

I have got 3 router A-->B--->C , I need to establish ebg neigbor between router A( RID :10.10.10.1 AS 64512) -->C ( RD :172.16.1.2 AS 65102 )

connection

rtr A to rtr B ----> int fast 0/0 to int fast 0/0 ( 10.10.10.0/30)

rtr B to rtc -----> int fast 0/1 to int fast 0/1 ( 172.16.1.0/30)

to accomplish bgp connection

from rtr A i need to point static route 172.16.1.0 255.255.255.252 10.10.10.2

similarly from rtr c i need point static route 10.10.10.0 255.255.255.252 172.16.1.2

Is there any other way apart from static route my ebg neigbor realtion will form between these both router .

Similarly if i use

bridge IRB at router B this is will isolate need for two IP subnet  , but my IP subnet 10.10.10.0/30 should be increased to 10.10.10.0/28 and also  there is no need  for static route at both router .

else suggest me how crb can be used over here if use 10.10.10.0/30

which will be best solution for this setup

Re: BGP help

Hello Sanvaishu. advertise the networks in BGP. Then you can get rid of the static routes.


On router c

router bgp 65102
neighbor 10.10.10.1 remote-as 64512
neighbor 10.10.10.1 ebgp-multihop
network 172.16.1.0 255.255.255.252

On router A

router bgp 64512
neighbor 172.16.1.2 remote-as 65102
neighbor 172.16.1.2 ebgp-multihop
network 10.10.10.0 255.255.255.252

please remember to rate this post if it helps

Re: BGP help

Hi,

IMHO, this will not work.

neighbor ... ebgp-multihop

is correct, but you need to know how to route to a BGP neighbor BEFORE the BGP session is established.

The static routes mentioned in the original question are a correct and easiest way.

BR,

Milan
