EIGRP seed metrics when redistributing
In order to successfully redistribute routes from other protocols into EIGRP, five seed metrics must be defined using the default-metric command. For example:
R2(config)#router eigrp 12 R2(config-router)#redistribute rip R2(config-router)#network 192.168.12.0 R2(config-router)#no auto-summary R2(config-router)#default-metric 1500 100 255 1 1500
If the default-metric command is not used, an infinite metric is used by default, thus no routes are redistributed.
Seed metrics are not used when redistributing static routes into EIGRP, or when redistributing routes from one EIGRP process to another.
