Applying an IPsec policy to an IPv6 BGP peer or peer group

To protect routing information and defend attacks, IPv6 BGP can authenticate protocol packets by using an IPsec policy.

Outbound IPv6 BGP packets carry the Security Parameter Index (SPI) defined in the IPsec policy. A device uses the SPI carried in a received packet to match against the configured IPsec policy. If they match, the device accepts the packet; otherwise, it discards the packet and will not establish a neighbor relationship with the sending device.

Configuration prerequisites

Before you apply an IPsec policy to a peer or peer group, complete following tasks:

For more information about IPsec policy configuration, see Security Configuration Guide.

Configuration guidelines

An IPsec policy used for IPv6 BGP can be only in manual mode. For more information, see Security Configuration Guide.
