Task
Specify the hash algorithm seed.
In Figure 14-1, Core Router 1 is an E-Series TeraScale and Core Router 2 is an E-Series ExaScale. They
have similar configurations and have routes for prefix P with two possible next-hops. When Deterministic
ECMP is enabled and the hash algorithm and seed are configured the same, each flow is consistently sent
to the same next hop even though they are routed through two different chassis.
