VPLS in VIRL using CSR1000v

[mmoraba]

Hi All

Can anyone provide me an example of extending vlan over VPLS using ios-xe. i am more interested about the CE config as the PE config is well demonstrated on the below link:

http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/mp_l2_vpns/configuration/xe-3s/mp-l2-vpns-xe-3s-book/mp-vpls.html#GUID-BAD7A7D4-0E29-4F48-8462-AF0A7FB9E4F1

However i want to see what the CE config looks like particularly with VLANs. Thanks!

Hello Mmoraba,

The CE's will usually have subinterfaces if they are routers or they will have SVI's configured and have a trunk interface towards your PE devices. The PE devices will then be configured with EVC to accept and put the Vlans in their respective bridge-domain which will then be sent across the pseudowire. 

You can take a look at the following config snipplet for a simple VPLS setup with XE devices as the PE's and carrying Vlan Tags.

Note that this setup may not work using VIRL XE devices. 

PE1:

PE1#sh run int g0/0/0      <<<< Attachment circuit towards CE1
interface GigabitEthernet0/0/0
 no ip address
 negotiation auto
 service instance 192 ethernet
 encapsulation dot1q 192
 bridge-domain 192

PE1#sh run | sec vfi 
l2 vfi VPLS1 manual 
 vpn id 192
 bridge-domain 192
 neighbor 110.2.2.2 encapsulation mpls

PE2:

PE2#sh run int g0/0/0
interface GigabitEthernet0/0/0
 no ip address
 negotiation auto
 service instance 192 ethernet
 encapsulation dot1q 192
 bridge-domain 192


PE2#sh run | sec vfi
l2 vfi VPLS1 manual 
 vpn id 192
 bridge-domain 192
 neighbor 110.1.1.1 encapsulation mpls

CE1:

CE1#sh run int g0/0/0.192 
interface GigabitEthernet0/0/0.192
 encapsulation dot1Q 192
 ip address 192.168.1.1 255.255.255.0

Hi Victor

Is this on ios-xe? particularly on CSR1000v? I see you also using the legacy syntax, does the new syntax produce same results?

[Victor Acevedo · Accepted solution]

Hey Mmoraba,

Yes, this is on a CSR1kv running IOS XE. You can use the new syntax as follows for the CE's

CE1#sh run int g0/0/0
interface GigabitEthernet0/0/0
 no ip address
 service instance 192 ethernet
 encapsulation dot1Q 192
 bridge-domain 192

CE1#sh run int bdi192
interface BDI192
 ip address 192.168.1.2 255.255.255.0
 encapsulation dot1Q 192

CE1#ping 192.168.1.1 
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms

CE2# sh run int g0/0/0
interface GigabitEthernet0/0/0
 no ip address
 service instance 192 ethernet
 encapsulation dot1Q 192
 bridge-domain 192

CE2#sh run int bdi192
interface BDI192
 ip address 192.168.1.1 255.255.255.0
 encapsulation dot1Q 192

CE2#ping 192.168.1.2 
Type escape sequence to abort.
