Hi Group,
I read the sections of the BGP configuration guide regarding
prefix-list and their configuration, but I can't seem to find where I'm making
a mistake. Scenario goes something like this:
Requirement: remove all prefixes with a mask longer that 20bits. I applied
the following route-map and prefix to neighbor 54.7.6.254 - direction IN ...
ip prefix-list 1 seq 5 permit 0.0.0.0/0 le 20
route-map FILTER-20 permit 10 <----- requirement for a previous task
disregard, unless this is the problem.
set weight 6000
route-map FILTER-20 permit 20
match ip address prefix-list 1
!
After "clear ip bgp * soft in | out " the table looks as follows:
BGP table version is 14, local router ID is 150.1.6.6
Status codes: s suppressed, d damped, h history, * valid, > best, i -
internal,
r RIB-failure
Origin codes: i - IGP, e - EGP, ? - incomplete

Shouldn't 28.119.16.0/24 and 28.119.17.0/24 getremoved from the routing
table?
Thanks,
