[c-nsp] Prevent traffic originated from the router usingaccess-list

[Jeff Tantsura]

Hmmm.  you could be right, sorry, haven't used anything else than 12K/7600
for years, so no chance to run 12.3T/12.4

 

Regards,

Jeff

Bollocks, It does not. You can't set "drop" action within policy-map
framework 

I don't need a lab for this.

The working config would be:

 

ip local policy route-map BLAH

route-map BLAH

 match ip address 101

 set interface null0 

 

access-list 101 permit ip host 192.168.5.254 any
access-list 101 deny any any

Hi,

It's not going to work, you'd only match on transit traffic, in order to 
match on locally generated traffic you should use local PBR ie:
ip local policy route-map BLAH
