Symptoms

MCPD accepts the wild-card IPIP tunnels with the same local-address and tunnel type (ip4ip6, ipip, ip6ip4, ip6ip6) without validation, although the configuration is eventually discarded in TMM.

Impact

This incorrect configuration is allowed on the BIG-IP system without error.

Conditions

Creating wild-card tunnels with the same local-address and IPIP tunnel-type.

Workaround

Specify wild-card tunnel using different local-address and tunnel-type.

Fix Information

Wild-card tunnel setup trials are now detected by BIG-IP system validation during creation time. The system disallows creation of wild-card tunnels with the same local-address and tunnel-type.
