Hi,When we configure the L2VPN L2 virtual circuit, we configure a far end peer IP and a VCID , what significance VCID has? Can we just put any value for VCID same or different on both the ends..For FR , I see it being dlciFor dot1, vlan I see it bein...
Hello,IS-IS DIS sends hellos at 3.3 seconds, so does it means 3.3 seconds between DIS and all other routers as well as other routers also send hellos to DIS at the same seconds...and IS-IS normall routers are exchanging hellos between them at 10 sec....
Hi,everyone!I've read some books about MPLS L2VPN. But I got some confusion about the conception of L2VPN interworking mode: IP and Ethernet.As I know, the differences between the two mode is the payload of the packets which transport in the PW. When...

Scenario of Inter-Vlan routing between PIX and L3 (SW 6509) Under the core routers sub-interfaces, the voice vrf is directly going to LVI of 6509 switch. But NON-MPLS traffic is directly going to gateway of backbone zone of pix.The details we have me...
All,I would need some advice on how to exchange route between 2 different vendor MPLS. See attach MPLS.gif for the proposed connection.1. Primary MPLS provider is Vendor "A"2. Due to no coverage from vendor "A", we must use Vendor "B" to connect Site...
I was wondering if in a EWS circuit, does the MPLS PE Router learn the MAC-Address or is it dependent on the way the Circuit is configured i.e. Type-4 and Type-5 or Sub-interface based or SVI based. Is there any way this MAC-learning can be disabled....
