Guidelines for Configuring Multipoint Receive-Only Tunnels
● You can configure up to eight remote end-points for a multipoint receive-only tunnel. The maximum number of remote end-
points supported for all multipoint receive-only tunnels on the switch depends on the hardware table size to setup
termination.
● The IP MTU configured on the physical interface determines how multiple nested encapsulated packets are handled in a
multipoint receive-only tunnel.
● Control-plane packets received on a multipoint receive-only tunnel are destined to the local IP address and routed to the
CPU after decapsulation. A response to these packets from the switch is only possible if the route to the sender does not
pass through a receive-only tunnel.
● Multipathing over more than one VLAN interface is not supported on packets routed through the tunnel interface.
● IP tunnel interfaces are supported over ECMP paths to the next hop. ECMP paths over IP tunnel interfaces are supported.
ARP and neighbor resolution for the IP tunnel next-hop are supported.
