%DCD!G BGP identifier wrong
Hi All,
R4 and R5 are directly
connecting and running OSPF and BGP, but BGP is not
working as follow:
r5#sho
ip bgp sum
BGP router identifier 170.241.127.228, local AS number 100
BGP
table version is 1, main routing table version 1
Neighbor V AS

And following is the error message:
