If there is a partial failure of the PPPoE client, no BRG or in-home device states are removed. All affected stacks no longer forwards traffic and any flow states may be removed. Setup of IPv4 hosts and routed (non-PPPoE client) devices continues. Existing SLAAC hosts are not removed, but a deprecation RA (with 0 lifetimes) is sent and no new SLAAC hosts are created.
The PPPoE client attempts to re-establish the connection, subject to the configured retry and backoff timers. Traffic is allowed again after the connection is restored. If a new IPv4 address is assigned, this is immediately applied as the new NAT outside address. If a new IPv6 prefix is assigned, IPv6 prefix replacement is triggered for existing SLAAC hosts.
If the peer MAC address changes during a reconnection, it may be hashed to a different NAT ISA. This is not supported by the system, and if it occurs, the entire BRG is removed.
