IRDP

Some functional changes are required in Internet Router Discovery Protocol (IRDP) to support IP multinetting. When IRDP is enabled on a Layer 3 VLAN (Virtual LAN), the ExtremeXOS software periodically sends ICMP (Internet Control Message Protocol) router advertisement messages through each subnet (primary and secondary) and responds to ICMP router solicitation messages based on the source IP address of the soliciting host.
