Customizing IP Services

Enabling Equal-Cost Multipath Support
IP equal-cost multipath support is a load-balancing feature that allows IP to
distribute traffic over multiple (up to five) equal-cost paths to the same destination.
By default, multipath support is disabled on the router: for each routing protocol,
IP stores the best next hop to a destination in the routing table. If traffic arrives on
an interface, IP determines the best route to the destination and forwards all
packets out the next-hop interface.
If multipath support is enabled, IP will distribute traffic among equal-cost routes
(if such routes are available). You can use Site Manager to enable multipath
support on the router and to specify whether IP distributes packets in a
round-robin fashion or uses a distribution method based on the source and
destination address of the packets.
•Inround-robin distribution, IP forwards each packet to a different next hop
until it reaches the end of the list of available next hops; then it repeats the list.
Round robin distribution makes full use of available resources but may cause
packets to be delivered out of order.
•Inaddress-based distribution based on the source and destination address, IP
forwards all packets with a given source and destination address to the same
next hop. This method increases the chances that the packets will be delivered
in order but does not take full advantage of available resources.
In address-based distribution based on the destination address only, IP
forwards all packets with a given destination address to the same next hop.
This method makes the forwarding algorithm compatible with RSVP when
RSVP is enabled on the router.
Both RIP and OSPF support equal-cost multipath routing. You can use Site
Manager to specify the number of equal-cost routes (up to five) that RIP and
OSPF will submit to the routing table manager. For instructions, see “Configuring
RIP for Equal-Cost Multipath Support” on page 4-8 and “Configuring OSPF for
Equal-Cost Multipath Routing” on page 5-13.
