With the following config I try to advertise a network to neighbor but the show command only list 0 prefixes to this neighbor.
router bgp 2 bgp log-neighbor-changes neighbor 126.96.36.199 remote-as 1 ! address-family ipv4 network 188.8.131.52 network 184.108.40.206 mask 255.255.255.0 neighbor 220.127.116.11 activate neighbor 18.104.22.168 route-map red out exit-address-family ! ip route 22.214.171.124 255.255.255.0 Null0 200 ! ip prefix-list 1 seq 5 permit 126.96.36.199/28 ! route-map red permit 10 match ip address prefix-list 1 !
On one interface there is the network 188.8.131.52/30 connected (BGP neighbor) and on a second interface there is the network 184.108.40.206/28 connected, this second network should be advertised to the neighbor.
This is the routing table:
#sh ip route | inc 128.16.16. S 220.127.116.11/22 is directly connected, Null0 C 18.104.22.168/28 is directly connected, GigabitEthernet0/0/0 L 22.214.171.124/32 is directly connected, GigabitEthernet0/0/0 C 126.96.36.199/30 is directly connected, GigabitEthernet0/0/1 L 188.8.131.52/32 is directly connected, GigabitEthernet0/0/1
This is the output of sh bgp command:
#sh bgp | inc 128.16.16. BGP table version is 39103822, local router ID is 184.108.40.206 *> 220.127.116.11/22 0.0.0.0 0 32768 i 18.104.22.168 0 1 i 22.214.171.124 0 1 i
And this one the show advertised route command:
#sh ip bgp neighbors 126.96.36.199 advertised-routes Total number of prefixes 0
If I delete the
neighbor 188.8.131.52 route-map red out command then the sh advertised route command contains all routes. How can I debug why the route don't advertise the route from route map.
