MSDP routing policies

MSDP routing policies allow for filtering of inbound and outbound SA messages. Policies can be configured at the following levels:

• global level

  This level applies to all peers.

• group level

  This level applies to all peers in a peer group.

• neighbor level

  This level applies only to specified peer.

The most specific level is used. If multiple policy names are specified, the policies are evaluated in the order they are specified. The first policy that matches is applied. If no policy is applied, source active messages are passed.

Match conditions include:

• neighbor

  This condition matches on a neighbor address is the source address in the IP header of the source active message.

• route filter

  This condition matches on a multicast group address embedded in the source active message.

• source address filter

  This condition matches on a multicast source address embedded in the source active message.
