N7K-1-Core1#<br />

Configuring BSRs<br />

The next RP configuration methodology is Bootstrap Router (BSR). In Example 4-5, N7K-1-<br />

Core1 is configured with both a bsr-c<strong>and</strong>idate <strong>and</strong> bsr rp-c<strong>and</strong>idate policy for groups in the<br />

239.0.0.0/8 range. This enables N7K-1-Core1 to participate in BSR elections <strong>and</strong>, if<br />

elected as a RP, apply a policy determining which routes will be advertised. N7K-1-Core1<br />

is configured to listen to BSR messages as well.<br />
