prefix list number limit on route map

[Myky]

Hi guys,

Is there a limit on how many prefix lists you can attach per one sequence number on route map for a single match?

route-map TEST, permit, sequence 6
Match clauses:
ip address prefix-lists: PL1 PL2 PL3 PL4 PL5 PL6 >>> how many (if there is a limit) I can attach per single match?

Thanks,

myky

why you do this ?
instead do this 
ip prefix-list MHM seq 5 permit ....

ip prefix-list MHM seq 10 permit ....

ip prefix-list MHM seq 20 permit ....

ip prefix-list MHM seq 30 permit ....

which is same as add many match prefix-list under route-map match.

please note that 

in match there is AND and OR

.

@balaji.bandi @MHM Cisco World thanks!

@MHM Cisco World that is certainly a valid option but we don't have much room between seq numbers (let's say) and also there is a lot of other stuff configured.

Check this discussion, one answer but dont mention the source of information that 500 acl can apply to pbr (to prevent delay).

Good question never come across any limitation, but we need to consider optimal matching, the more means more processing conditions.

Note : happy to hear that limitation.

Hi @Myky ,

There is a maximum number of characters per line, but I do not think there is a hard limit to the number of prefix-list you can specify on multiple lines.

route-map test permit 10
