Paresh, I believe Alcatel's Dimitri P is co-author of the below mentioned draft which is being marketed at MPLS-WG for using RSVP-TE as PSN signalling proto. Cutting aside the politics behind the draft... Can anyone highlight the advantages using Rsvp.. apart from Qos for PSN's. Regards, Aditya http://www.ietf.org/internet-drafts/draft-raggarwa-rsvpte-pw-03.txt P.S-Interesting to note,none of the vendors on the draft seem to have implemented it yet.

Deborah, As far as Option B goes, you need to have MP-eBGP session between the ASBR's which are directly connected. They will redistribute the VPN-IPv4 labels of it's AS to the ASBR. You can have multiple ASBR-ASBR Ebgp session incase there are many VPN's or if you want redundancy(L-Pref). Option C The redistribution of the VPN-IPv4 routes can happen via Multi-Hop MP-BGP session between the PE's or RR's. The ASBR will not hold any VPN-IPv4 labels or redistribute them,but has to have an /32(loopback) labeled route for PE in its AS and will redistribute this to the other AS. This is the Igp Label(PE Loopback) which will enable a packet to be forwarded from the Ingress PE to the Egress PE(LSP from Ingress PE to Egress PE). Incase the /32 label is also redistributed to the P routers also... it will require a label stack of 2 labels. If they are unkown to P routers the label stack required will be 3. The bottom label will be the VPN-IPv4 label, middle label will be the Egress PE label redistributed by the ASBR of its AS and the Top label will be assigned by the Ingress PE to reach its ASBR. Coming back to the your question the major difference between option A and B are. OptionB-ASBR redistributes VPN-IPv4 labels. OptionC-ASBR doesn't hold any VPN-IPv4 labels. As far as I can understand,you can have multiple ASBR's in all the 3 Options. Regards, Aditya ... View more

Nisha, As Harold specified, You have to first specify the PE's(Site) which will be part of the VPLS instance. This will enable the Pseudowires to the respective PE's and signal a T-LDP session for the VC label exchange. This ldp session(Tcp) will require a Transport address....which requires a L3 address. This is as far as control plane signalling of the VC labels is concerned. As far as Data plane is concerned when the l2 frames arrive at ingress i/f there is an imposition of 2 labels...ie VC label which is used to define the egress interface on the Egress PE and Igp label which is used to forward the packet till the Egree PE(PW-Tailend. VPLS is a layer 2 technology riding on a l3 MPLS Network. Pls refer the below mentioned draft's for a better understanding of the same. Hope this helps.

If u are going to use 6509 as a Switch....u dont need any Mpls feature on the 65. U just need to increase the Mtu size on the 65 for carrying labeled packets. Below is snapshot for calculating Mtu size in an Mpls environment. MPLS Label Stack The MPLS label stack size depends on the configuration of the core MPLS network. AToM uses one MPLS label to identify the ATOM VCs (VC label). Therefore, the minimum MPLS label stack is 1 for directly connected ATOM PEs, which are PE routers that do not have a P router between them. If LDP is used in the MPLS network, the label stack size is 2 (the LDP label and the VC label). If a TE tunnel instead of LDP is used between PE routers in the MPLS network, the label stack size is 2 (the TE label and the VC label). If a TE tunnel and LDP are used in the MPLS network (for example, a TE tunnel between P routers or between P and PE routers, with LDP on the tunnel), the label stack is 3 (TE label, LDP label, VC label). If you use MPLS Fast Reroute in the MPLS network, you add a label to the stack. The maximum MPLS label stack in this case is 4 (FRR label, TE label, LDP label, VC label). Example of Estimating Packet Size The example uses the following assumptions: The edge MTU is 1500 bytes. The transport type is Ethernet, which designates 18 bytes for the transport header. The MPLS label stack is 2, because LDP is used. The MPLS label is 4 bytes. Estimating the MTU for Packets Edge MTU + Transport header + (MPLS label stack * MPLS Label) = Core MTU 1500 + 18 + (2 * 4 ) = 1526 ... View more
