Hi Community,
Currently the 3 Routers are managed by us, now customer informed us that they will advertise a LAN Prefix via BGP
12.212.0.0 /16
Note: after the Router there are FW facing the other networks cloud
In which we created an ACL for it
access-list 110 remark ** LAN PREFIX **
access-list 110 permit ip 12.212.0.0 0.0.255.255 any
After that we are able to received routes from the LAN prefix
R1#show ip bgp neighbors 10.220.189.112 received-routes | inc 12.212
*> 12.212.0.0/16 10.220.189.112 87 0 131470 ?
R1#show ip bgp neighbors 10.245.195.115 received-routes | inc 12.212
*> 12.212.0.0/16 10.245.195.115 87 0 131470 ?
R1#show ip bgp neighbors 10.240.192.121 received-routes | inc 12.212
*> 12.212.0.0/16 10.240.192.121 91 0 136571 136571 136571 ?
The customer requested to see the IP Nat translations, as per checking we are unable to see any translated IP from the LAN prefix but we are able to see other LAN segments from same AS being translated.
What I can see on the Config is that it is overloaded to the Loopback 0 but i am not sure how come other segments are being translated yet the received routes is not translated.
I just want to have some clarification how it works.
