The BGP session from PE to P is not operational

The BGP session between PEs is not operational

In the CSC VPRN, configure an eBGP session between CSC-PE and CSC-CE and use the "advertise-label vpn-ipv4" CLI command to enable the advertisement of VPN-IPv4 routes.

When the customer carrier uses the same autonomous system number in various sites, use the "loop-detect off" CLI command to disable the loop detection functionality on CSC-CE and PE routers.

On the CSC-PE routers, use the "carrier-carrier-vpn" CLI command to configure the VPRN service as CSC.

Configure an iBGP session between PE1 and PE2 and use the "family vpn-ipv4" CLI command to directly exchange end-customer routes learned from CE1 and CE2.

PE1 sends an IPv4 update for prefix 192.168.1.0/27 via MP-BGP to ASBR1.

ASBR1 sends an IPv4 update for prefix 192.168.1.0/27 to ASBR2.

ASBR1 transforms an IPv4 update for prefix 192.168.1.0/27 to a VPN-IPv4 route; allocates VPN label V1 and sends the update to ASBR2.

ASBR2 accepts a VPN-IPv4 update from ASBR1, then sends the update to PE2 via MP-BGP.

When the P receives the route from the PE.

When the PE populates the route received from the CE into the VRF.

When the PE propagates the route to the CE.

When the PE exports the route from the VRF into the MP-BGP table.

Reduced number of VPN tunnels that need to be managed

Centralized filtering policies with the introduction of a hub site

Optimal routing between all sites

Limited configuration required on the hub PE device

The protocol is configured under the config>service context

The protocol is configured under the global router context

The interface leading to the PE is defined as a protocol neighbor

The routing protocol used must be the same as the routing protocol used at other CE-PE locations in the same VPN.

A routing policy may or may not be required depending on the routing requirements and routing protocol

PE1 pushes an LDP transport label.

CSC-CE1 pops the LDP label and pushes a BGP label.

CSC-PE1 pops the BGP label and pushes two labels: a VPN label and an MPLS transport label.

CSC-PE2 pops the MPLS label and pushes a BGP label.

The VPRN ID must be the same value as is used in the vrf-target command

The VPRN ID must be the same value as is used in the route-distinguisher command

The router-id command should not be used in this context

The vrf-target command is mandatory

There is nothing wrong with this configuration
