Re: [j-nsp] Usage of Route distinguisher in VPLS

Suppose multiple sites end up using the same Site-id (VE-id) but participate in different VPLSs(differnent RTs) then RD will help distinguishing the layer-2 bgp-nlri for the layer2-routes for these sites. Isn't it? Else (if RD is same or non-existent), advertisement for one site will mask the othe

Re: [j-nsp] Usage of Route distinguisher in VPLS

Thanks for the reply. As per section 3.1.2, Route target only identifies the VPLS. Even in Juniper, if I have a configuration like this, root# show routing-instances vplsinst2 { instance-type vpls; route-distinguisher 100:4; vrf-target { import target:100:3; export targ

Re: [j-nsp] Usage of Route distinguisher in VPLS

Hi Monika, I haven't played around much with VPLS but a quick read of RFC 4761 reveals the following... Section 3.5 of RFC 4761 appears to be the key. It refers to multihoming mechanisms for VPLS and states the following... In the case where the PEs connected to the same site are assigned th

Re: [j-nsp] Usage of Route distinguisher in VPLS

Thanks for your replies I think there was a confusion in my query. My question was to understand why Route distinguisher is proposed in VPLS NLRI? What is the use of sending RD in the NLRI? With MP-BGP, there are two extensions for VPN application. 1 - L3VPN (RFC 4364) and L2 VPN (RFC 4761) both o

Re: [j-nsp] Usage of Route distinguisher in VPLS

Hi Monika, You can check with RFC 4761. Generally, NLRI for VPLS format is as following: ++ | Length (2 octets)| ++ | Route Distinguisher (8 octets)| +-

[j-nsp] Usage of Route distinguisher in VPLS

Hi, In L3VPN, The purpose of the Route Distinguisher is solely to allow one to create distinct routes to a common IPv4 address prefix. But why do we need Route distinguisher for VPLS? Was this added to VPLS to be consistent with L3VPN? -Monika
