How does multiple "set" statements in Route-map for PBR work

[geons]

Hello 

I have a situation in PBR,  where there are two "set" statements in route-map as below,

route-map ABCD permit 10
 match ip address ACCESS_LIST1
 set ip next-hop verify-availability 10.10.10.10 1 track 1
 set interface Null0

I understand that first set statement will set the next hop as 10.10.10.10 , if the track is up. But I am not sure about the second set statement as it drops the packet (that's what i understood from null0)

Really appreciate the help

Thanks

set interface Null0 - the default interface is the Null0 interface. Setting this will force the router to discard the packets rather than use the router general default gateway.(if anything setup)

If the packets you want to drop do not match either of the  route-map clauses, then change set  default interface null0 to set interface null0.

Thank you soo much for your response.

Sorry, I am little confused, can you clarify "If the packets you want to drop do not match either of the  route-map clauses, then change set  default interface null0 to set interface null0"

i mean - example IPv4 PBR to send all traffic to the null interface, thus dropping the traffic instead of forwarding it.

Hello

My understanding is the same,

PBR will attempt next hop first and if that isnt avaiible then interface will then be attempted.
