Hi, Group,
I am doing CCIE practice kit chapter 2: A case study
in BGP. in Question 55 about route damping.
The requirement is to allow route-dampen 152.1.13.0
network in neighbor AS. The solution is as follows:
in router r3
*************************
router bgp 100
no synchronization
bgp log-neighbor-changes
bgp dampening route-map damp
------
route-map damp permit 10
match ip address 20
set dampening 10 80 1100 120
---------------
access-list 20 permit 152.1.13.0 0.0.0.255
-----------
scenario:
AS200 AS100
R4------------------------------R3
lo0 152.1.13.0/24
*****************************
But I never get it to work.
Question 1: if i use directly
*************
router bgp 100
bgp dampening
***************
in R3, the route will be suppressed.
what's the difference here? I am confused. I think
that route-map should work.
Question 2. If there is a default route to 0.0.0.0 in
R3, then i never see the route is marked as
suppressed. As show ip bgp 152.1.13.0 always shows
another router ( default next hop) as next hop to
152.1.13.0 even though the route is not shown in BGP
table.
Am I missing something here or what's the right way?
any help will be greatly appreciated
Regards
michael
