Hi Group,
I have the following config:
SW2:
!
router bgp 65078
no synchronization
network 150.1.8.0 mask 255.255.255.0
aggregate-address 150.1.0.0 255.255.240.0 summary-only
no auto-summary
!
The aggregate goes into the RIB as follows:
B 150.1.0.0/20 [200/0] via 0.0.0.0, 00:00:01, Null0
I'd like to prevent it from entering the RIB. I can think of two methods:
Method 1
--------
!
router bgp 65078
distance bgp 20 200 255
!
Method 2
--------
!
router bgp 65078
distribute-list prefix DENY_AGG in
!
ip prefix-list DENY_AGG seq 5 deny 150.1.0.0/20
ip prefix-list DENY_AGG seq 10 permit 0.0.0.0/0 le 32
!
Both methods work. Can anyone advise me, in general what should I watch out
for if I were to use any of the above methods in a lab scenario?
Thank you.
BR,
Emil
