RE: Expanding the VLAN over the WAN

Thanks a lot Adam, i am checking L2TPV3 Vs VPLS and also the below
configuration
http://www.cisco.com/en/US/solutions/collateral/ns340/ns517/ns224/ns949/ns304
/ns975/product_bulletin_c25-602184.html And also the below confiruation will
it work over the WAN: First of all make sure if both switches support IRB.

FOR
SW1

int vlanX (VLAN A)
bridge-group 1
 int fas 0/1
bridge-group 1
 int bvi 1
ip address 10.10.10.1 255.255.255.252
ip address x.x.x.x x.x.x.x secondary (VLAN A SUBNET)
FOR
SW2

int vlanX (VLAN A)
bridge-group 1
 int fas 0/1
bridge-group 1
 int bvi 1
ip address 10.10.10.2 255.255.255.252
ip address x.x.x.x x.x.x.x secondary (VLAN A SUBNET)
 with this configuration you have EXTENTED VLAN A SUBNET without loosing the
routing subnet between both switches.

Hi John,

For point-to-point services you could look at PWE3 psuedowires using L2TPv3,
it tends to be supported on a fair range of platforms without requiring
special hardware.

Cheers,
Adam

Good day everybody, is thery any way to expand the VLAN over the WAN. I think

Nexus OTV will do that. But is there any way we can do this by configuration

rather than getting new hardware. thanks a lot.
