A related question is why are we able to omit the metrics when redistributing?
I did this with RIP and couldn't figure out why redistribution silently did
nothing until I put the metrics in. This is from the first lab in IE vol
4.1:
Without metrics, a downstream neighbor's external eigrp routes:
D EX 204.12.1.0/24 [170/20537856] via 183.1.28.2, 1d00h, Vlan28
D EX 183.1.39.0 [170/20537856] via 183.1.28.2, 1d00h, Vlan28
D EX 183.1.0.0 [170/21024256] via 183.1.28.2, 00:34:34, Vlan28
Now the only thing I add is the metrics and the same downstream neighbor
sees:
D EX 222.22.2.0/24 [170/20566016] via 183.1.28.2, 00:06:43, Vlan28
D EX 204.12.1.0/24 [170/20537856] via 183.1.28.2, 1d23h, Vlan28
D EX 220.20.3.0/24 [170/20566016] via 183.1.28.2, 00:06:43, Vlan28
D EX 183.1.39.0 [170/20537856] via 183.1.28.2, 1d23h, Vlan28
D EX 183.1.0.0 [170/21024256] via 183.1.28.2, 22:58:14, Vlan28
The upstream configs are:
First example:
router eigrp 100
redistribute rip
Second example:
router eigrp 100
redistribute rip metric 10000 100 255 1 1500
With a few exceptions, secrecy is deeply incompatible with democracy and with
science.
