on router F.

Figure 7-3. IBGP ECMP Traffic Balancing
You can use the BCC or Site Manager to configure IBGP for ECMP route
balancing and traffic balancing.
Using the BCC
To configure IBGP for ECMP route or traffic balancing, go to the BGP prompt
(for example,
box; ip; /jointfilesconvert/97454/bgp) and enter:
i/jointfilesconvert/97454/bgp-ecmp-method
<method>
method
is one of the values described in Table 7-1.
For example, the following command configures BGP for IBGP ECMP traffic
balancing:
/jointfilesconvert/97454/bgp#
i/jointfilesconvert/97454/bgp-ecmp-method traffic-balance
/jointfilesconvert/97454/bgp#
Table 7-1. IBGP ECMP Methods
Method Meaning
route-balance BGP submits one BGP route to the IP routing table for each BGP
destination, using in turn (round-robin) the available IGP ECMP
routes to the next hop.
traffic-balance BGP submits multiple routes to IP, using all known IGP ECMP next
hops.
disabled (default) IBGP implements neither route nor traffic balancing.
