11.10 Multiple Routers Support
Multiple routers support is designed to assist the device when it operates in a multiple
routers network. The device learns the network topology by responding to Internet Control
Message Protocol (ICMP) redirections and caches them as routing rules (with expiration
time).
When a set of routers operating within the same subnet serve as devices to that network
and intercommunicate using a dynamic routing protocol, the routers can determine the
shortest path to a certain destination and signal the remote host the existence of the better
route. Using multiple router support, the device can utilize these router messages to
change its next hop and establish the best path.
Note: Multiple Routers suppo
configuration.
11.11 IP Multicasting
The device supports IP Multicasting level 1, according to RFC 2236 (i.e., IGMP version 2)
for RTP channels. The device is capable of transmitting and receiving multicast packets.
