When i am seeing debug of bgp updates and events, i got "recursion error routing loop" for one ip address say 172.16.1.1/30.
I am having two providers, say A & B. With B, asymmetric TX and RX circuits. The IP address 172.16.1.2 is for the asymm TX interface to B.
So, by default, 172.16.1.1/30 is directly connected to me. But i am getting BGP route update for 172.16.0.0/16 network from A, at that time giving the "recursion routing loop" error in my debug messages.
Thanks in advance...
With best regards...
Pls kindly rate if helpful or answered your question.
To understand the reason behind why recursive routing is failing in tour situation, you need to understand how the routing algorithm works. For any nondirectly-connected route in the routing table whose next hop IP address is not a directly-connected interface of the router, the algorithm looks recursively into the routing table until it finds a directly-connected interface to which it can forward the packets.
