EVC | Allowing multiple vlans.

Hi Everyone,

Just a quick question about EVC Trunk EFP | Allowing multiple tags.

I'm currently working on this setup and I would like to seek your opinion and expertise about this setup.

From Customer they will send multiple tag (3320-3322). But in this scenario, I only inputted sub-int of .3320.

Supposed to be if Customer frame enters @ ASR920 G0/0/13 int it will match the EFP criteria last process if using ingress is the "bridge-domain from-encap" that means it will derive bridge-domain based on the encapsulation.

Under bridge-domain I'll have the these for formarding.

Bridge-domain 3320 (2 ports in all)

State: UP Mac learning: Enabled

Aging-Timer: 300 second(s)

Maximum address limit: 16000

GigabitEthernet0/0/13 service instance 203

TenGigabitEthernet0/0/27 service instance 100

Question:

1. Is this configuration is correct? (Though, I'm having issue with IP reachability so I'm checking which side has an issue)

PE#ping vrf custA 10.1.1.2 source 10.1.1.1.....Success rate is 0 percent (0/5)

1. Based on this interface output, when I try to ping toward to customer from PE, there;s now increasing rate on ASR920 interface?

ASR920#sh interface GigabitEthernet0/0/13GigabitEthernet0/0/13 is up, line protocol is up5 minute input rate 0 bits/sec, 0 packets/sec5 minute output rate 0 bits/sec, 0 packets/sec

1. Can't detect any mac address even the IP address on 10.1.1.1 for example?

Any docs/Materials about EVC you can share other than Cisco docs or docs posted on the internet?
