Hi guys,
Please help me with this little issue.
How does set ip next-hop suppose to work? let say I have R1 and R2. R1 has a
s1/0 interface to ISP router and it is configured for PBR for any traffic
originating from internal lan say subnet 10.10.10.0/24. The next hop is set
for ISP interface i.e
route-map blah permit 10
match ip address 1
set ip next-hop 172.1.1.2
Now Scenario1>>assume ISP next hop is NOT reachable and interface s1/0 is in
up/down state. Will router try PBR first and then normal routing or kept
trying PBR, hence dropping all 10.10.10.0/24 traffic?
Scenario2>> assume ISP next hop is NOT reachable and interface s1/0 is in
down/down state. Will router try PBR first and then normal routing or kept
trying PBR, hence dropping all 10.10.10.0/24
I am seeing traffic is blackholed ONLY when s1/0 is down/down otherwise R1
uses normal routing and routes 10.10.10.0/24 network via iBGP etc.
Please help as according to doyle's book even with up/down, the traffic
should be blackholed.
I have no way of verifying it but appreciate your help here.
