Elements
In this example we will configure VPLS
on our PE routers (XR1 and XR2); the clients will be R1 and R2 which will run
EIGRP between them
ISIS is the IGP used inside the
backbone; we will list the configuration from XR1 and XR2 side only

One note
to mention is that I have XR1 G0/1/0/0 interface to SW1 G0/1 interface , XR2
G0/4/0/1 connected to SW2 G0/2 interface , F0/20 – 21 bundled as etherchannel
on both switches and configured as trunk as the previous mentioned interfaces
(SW1 G0/1 , SW2 G0/2)
I faced
a problem in the mac-address flapping so I removed the vlan 12 (VPLS vlan in
function) from both trunks on both switches
SW1
interface
G0/1
switchport
trunk allowed vlan remove 12
SW2
interface
G0/2
switchport
trunk allowed vlan remove 12
