8 important questions on Last Additions - EIGRP

What is EIGRP Offset and what is it used for?

It is used as a more granular option to alter EIGRP routes. Instead of changing all routes learned on an interface by changing the interface delay, using the Offset option filtering can be used based on Update Direction, Specific Prefix or a combi.

In EIGRP, what does the Leak-Map option add when creating a summary route?

It adds the possibility of routes matching the route-map in the leak map option to be advertised alongside the summary route.

What routes are advertised by an EIGRP Stub Router?

Only Connected and Summary routes by default.
Can be configured to only receive routes or advertise any combination of redistributed routes, connected routes and summary routes.

What are EIGRP K Values?

It are the values used in EIGRP Metric calculation.
Can be changed with the command 'metric weights TOS K1 k2 k3 k4 k5 k6'
TOS is always zero and K6 is used for EIGRP Named configuration.
The values are part of the Hello packet.
They have to match between neighbors.

How can the K values of a router be looked up?

By using the Show IP Protocols command

What 2 commands are used to verify Keychain and Authentication settings?

Show Key Chain
To verify the keychain

Show IP EIGRP Interface Detail
To verify EIGRP Authentication on a specific interface.

What is the default AD and Seed Metric for redistributed External EIGRP routes?

When distributed to other protocols:
AD of 170
Seed Metric of Infinity

When distributed to EIGRP the path metrics are preserved.

In EIGRP, what is the Variance Value?

A value which is the result of the Variance Multiplier x Feasible Distance of the successor.
The Feasible Distance of the Feasible Sucessors are checked againt this value, and when lower, EIGRP installs these routes into the RIB, which enables Unequal Cost Load Balancing.
