Figure 14: Direct Next Hops
Indirect next hops enable multiple routes in the routing table to point to a single next
hop, thereby accelerating convergence. (See Figure 15 on page 132.)
NOTE: Indirect next hops are not limited to any number of levels. In other words,
an indirect next hop can point to a direct next hop or another indirect next hop.
Figure 15: Indirect Next Hops
By using indirect next hops, if a topology change occurs in the network, only the
indirect next hop is modified in the routing table, decreasing the number of state
changes required to achieve convergence.
