Severity: 3-Major

Symptoms

MLD snooping switches may not deliver router solicitation packets to BIG-IP, which breaks BIG-IP's router advertisement functionality. MLD snooping switches may not deliver the packets because BIG-IP has not joined the FF02::2 multicast group.

Impact

IPv6 hosts never receive router advertisements from BIG-IP in response to their router solicitations.

Conditions

router-advertisement configured, MLD snooping switches.

Workaround

Disable MLD snooping on switches.

Fix Information

BIG-IP now joins the FF02::2 multicast group when router-advertisements are configured.

Behavior Change

BIG-IP now joins the FF02::2 multicast group when router-advertisement is configured.
