Allow layer 3 traffic

This topic describes how different types of Layer 3 traffic are handled through bridge groups and the access rule requirements for each traffic type.

  • Unicast IPv4 and IPv6 traffic requires an access rule to be allowed through the bridge group.

  • ARPs are allowed through the bridge group in both directions without an access rule. ARP traffic can be controlled by ARP inspection.

  • IPv6 neighbor discovery and router solicitation packets can be passed using access rules.

  • Broadcast and multicast traffic can be passed using access rules.
