Configuring ePBR on the NCS540

[config]

Hi team, 

I am trying to configure ePBR on NCS540 (iosxr). When I try to attach the classes map "cm-providerz-tenanta", to the policy-map type pbr "pm-providerz-clients", I get an error. The command "show configuration failed" writes that cm-providerz-tenanta does not exist. But the current configuration has cm-providerz-tenanta. You can see it in the screenshot I attached. Can you please suggest other ways to customize epbr on NCS540? Thanks

When i were configuring ePBR on the NCS 540, I ran into another problem. Cisco bug serach tool described this problem here https://bst.cisco.com/quickview/bug/CSCvy21699 . Can you tell me if this problem is fixed in the new OS?

Hi @config ,

Your class-map needs to be of type traffic as follow:

class-map type traffic match-any cm-providerz-tenanta
match access-group ipv4 al-providerz-tenanta
end-class-map
!

Please delete it and reconfigure it and it should work.

@Harold Ritter  faster than me 
you dont specify the class type 
you need to specify type by 
class-map type traffic match-any cm-providerz-tenanta

and also under policy use 
class type traffic <name>

NOTE:- for default as I mention before use transmit

thanks

When i use specify the class type "traffic" in class-map cm-providerz-tenanta, i can't match access-group "al-providerz-tenanta". I have attached screenshot below.

class-map type traffic match-any cm-providerz-tenanta
match access-group ipv4 al-providerz-tenanta

if not work share the ACL you use in class map

Hi @config ,

It looks like a limitation specific to the NCS540. What does your ACL look like. You could maybe use some other forms of filtering (such as match source-address or destination-address) as suggested by the following document:

@Harold Ritter Thank you. That helped. And I found out that pbr is configured in vrf, not in the interface.
