Update- The original title should be referred to as EIGRP Virtual-Instance (that does support the legacy 32-bit metric and just might also support the 64-bit wide metrics; depending on your configuration).
Viewing the show command (Show command 1) based on EXAMPLE CONFIG 1 below, it's clear the K6 value is not used; only the K1 - K5 values.
If address-family vrf was implemented, as shown in EXAMPLE 2, it's clear the new wide-metric is in effect.
The question still remains, how does an EIGRP peer configured to recognize link speeds greater than 10Gbps interact with EIGRP peers that are not operating in 64-bit mode? What do the configurations look like for each of the peers?
ANYONE know?
Thanks
Frank
