Hi,
I am trying to have MP-BGP with my Access Router to Route Reflector first without enabling Acess to core interface as MPLS ( ip mpls)..Do you think that can be issue ?

HI Chintan, [Pls Rate if HELPS]
First you need to enable the interfaces with below configuration:
mpls label protocol tdp
tag-switching mtu 1546
tag-switching ip
only then the MP-BGP Sessions will be formed successfully.
Hope I am informative.
Pls RATE if HELPS

Layer 3 VPNs can be implemented in conjunction with L2TPv3 tunnels. The solution lends itself to implementation where the SP does not implement MPLS transport mechanism in the core to forward packets. Implementation of L2TPv3 tunnels creates a tunnel network as an overlay to the IP backbone, which interconnects the PE routers to transport VPN traffic. The multipoint tunnel uses BGP to distribute VPNv4 information between PE routers. The advertised next hop in BGP VPNv4 triggers tunnel endpoint discovery. Dynamic L3 VPN implementation over multipoint L2TPv3 tunnels provides the ability for multiple service providers to cooperate and offer a joint VPN service with traffic tunneled directly from the ingress PE router at one service provider directly to the egress PE router at a different service provider site.

Hi Guru Prasad,
Thanks for you response but I could do some test in my lab and found that MP-BGP can come up even without enabling MPLS on interface.
In live network, I am trying to integrate one of non-MPLS enable in to MPLS and before I enabled interface with MPLS, I want to have MP-BGP with VPNv4 RR but some how it is not comming up. Howerver after doing my test in lab it is clear that MPLS not required to enable to get MP-BGP up.

Are the two peers Cisco devices?

Hi,
No.These two peers are not cisco devices.
One is Juniper and other is Cisco.
Could you let me know where could be issue ?

Chintan,
According to the error message, the BGP open message sent by the Juniper peer is corrupted.

so that agree with what i have said earlier mate
it dose not need mpls
mpls for faster forwarding and to decrease the cpu load on the P routers
rate if useful
and about the error sorry i ahve no idea
good luck

Hi,
i would like to share here that my issue is resolved.Unfortuanly, Juniper doesn't work like cisco and we need to enable MPLS globally to negotiate VPNV4 capability with MP BGP peer. It means MPLS is required in Juniper but not in Cisco.
Thanks everyone.

Chintan.

you can use map-bgp without mpls enables.
MPLS a way of label switching. as long as you have your VRFs and its RDs and RTs enables and configured properly you can use mp-bgp without mpls
there is a way that ISP and cisco support it for ISP network that dose not have MPLS enabled in its network which it l2tpv3 tunnels
maybe you can use it aswel
search for it there is many documentations on cisco.com about lstpv3 tunnels
good luck
