RE: BGP - Suppressed Routes

Hi Udo,

It seems that you are doing BGP aggregation with the "summary-only"
keyword. As per your output below, it seems that you are sending an
aggregate of 174.1.0.0/16. That causes the more specific routes (that is
174.1.1.0 - 174.1.4.0 and so on) to be suppressed on the router
generating the aggregate.

Regards
Mohamed ...

Subject: BGP - Suppressed Routes

Hi all,

right now I working in my lab with bgp ..
When I have a look at the output 'show ip bgp' I saw routes with the
following states
================snip==================================================
...
s>i174.1.1.0/24 150.1.1.1 0 100 0 ?
r>i174.1.3.0/24 174.1.13.3 0 100 0 (65038) i
s>i174.1.4.0/24 150.1.4.4 0 100 0 i
s>i174.1.7.0/24 150.1.6.6 0 100 0 (65038
65267) i
...........
============snap=====================================================

can anyone explain me why are two routes in the 's' state ?
This routes are redistribute from two peers.

What does it exactly mean 'suppressed' and what is a possible reason for
this behavior

THX
Udo
