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 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.

Resources consumed at the sender and receiver PEs can be reduced by using BGP ORF.

BGP ORF allows a receiving PE to filter out unnecessary inbound routes.

A PE indicates its ORF capabilities to its neighbor PE in a BGP Open message.

BGP ORF is most effective when a large number of routes is being exchanged between two peers, and most routes are filtered out on arrival.

Scheduling

The primary contributors to latency are distance, scheduling, and congestion.

The weighted round robin scheduling algorithm will result in more delay for high priority traffic than the regular round robin algorithm.

The round robin scheduling algorithm will result in less jitter for low priority traffic than a strict priority scheduler.

Packet loss can be reduced by decreasing the amount of buffer space available to a queue.

Latency can be reduced by increasing the amount of buffer space available to a queue.
