Fiber SFP Gigabit Ethernet

Most of the vendors won't allow auto-negotiation. If there is mismatch, the Interface will become down/down.

Cisco Switch (C4900)
For fiber Gigabit Ethernet interfaces, the default is no speed nonegotiate, which sets the speed to 1000 Mbps and enables link negotiation for flow-control parameters and remote fault information. The speed nonegotiatecommand disables link negotiation.

Router:

no negotiation auto

Full Duplex, 1000Mbps, link type is force-up, media type is LX  (when nonegotiate)

Full Duplex, 1000Mbps, link type is auto, media type is LX  (when auto negotiate)

EIGRP Redistribution

EIGRP redistribution

There is no default metric for EIGRP so you need to manually configure metric when you redistribute routes from other routing protocol. But there are some exceptions:

1. Static route using next hop
          EIGRP will redistribute the static route using the exiting (next hop) interface's metric

2. IGRP
          If they have the same AS number, it will automatically redistribute between each other. Otherwise you need to manually configure but not need to configure metric.

3. Static route using interface
          You can use network statement (EIGRP internal route) or redistribute static (EIGRP external route) to advertise the route.
