Redundant Private Links With Diverse VXCs

Redundant Private Links With Diverse VXCs

A single VXC depends on one port at each end. How to design redundant private connectivity on the fabric.

Where the risk is

A VXC depends on your port, the partner’s port and the fabric between them. If either port fails, the VXC goes down.

Design for redundancy

  • Each party connects with two ports, ideally on different devices or in different locations.
  • Create two VXCs, one between each pair of ports.
  • Run BGP over both, with one preferred or both active.

Location diversity

For critical relationships, terminate the two VXCs in different Peer1IX facilities.

Test

Disable one VXC during a planned window and confirm that traffic fails over within your expectations.
