Configuring BFD <strong>for</strong> VRRP<br />

When using BFD with VRRP, <strong>the</strong> VRRP protocol registers with <strong>the</strong> BFD manager on <strong>the</strong> RPM. BFD<br />

sessions are established with all neighboring interfaces participating in VRRP. If a neighboring interface<br />

fails, <strong>the</strong> BFD agent on <strong>the</strong> line card notifies <strong>the</strong> BFD manager, which in turn notifies <strong>the</strong> VRRP protocol<br />

that a link state change ocurred.<br />

Configuring BFD <strong>for</strong> VRRP is a three-step process:<br />

1. Enable BFD globally. See Enabling BFD globally on page 604.<br />

2. Establish VRRP BFD sessions with all VRRP-participating neighbors.<br />

3. On <strong>the</strong> master router, establish a VRRP BFD sessions with <strong>the</strong> backup routers. See page 616.<br />

BFD sessions can be established <strong>for</strong> all VRRP neighbors at once, or a session can be established with a<br />

particular neighbor.<br />
