This link has a table with the distances and fiber supported per GBIC:http://www.cisco.com/univercd/cc/td/doc/product/lan/cat5000/cnfg_nts/ethernet/5399_01.htm#xtocid44297
You can specify an unlimited number of secondary addresses per interface. It would look like this:interface vlan 10ip address 10.1.1.1 255.255.255.0ip address 10.2.2.2 255.255.255.0 secondaryip address 10.3.3.3 255.255.255.0 secondarysee the followin...
HSRP can track interfaces where VRRP can not. Interface tracking allows you to specify another interface on the router for the HSRP process to monitor in order to alter the HSRP priority for a given group. If the specified interface's line protocol g...
