TFTP Transfer on a VRF Using ip tftp source-interface Command

I was trying to transfer an IOS image via TFTP to a remote Cisco router but it got timed out. My troubleshooting showed the TFTP server was only reachable from a VRF and not via the router's global routing table.


Router#copy tftp://172.27.5.4/c2900-universalk9-mz.SPA.155-3.M6a.bin flash
Destination filename [c2900-universalk9-mz.SPA.155-3.M6a.bin]?

I configured the ip tftp source-interface <INTERFACE> command and TFTP transfer worked afterwards.

Configuring EIGRP Load Balancing via Variance Command

Variance lets you tell Cisco IOS that the EIGRP metrics can be close in value and still be considered
worthy of being added to the routing table and you can define how close.The variance multiplier EIGRP router subcommand defines an integer in the range of 1 through 128. The router then multiplies the variance by the successor route’s FD - the metric of the best route to reach that subnet.

Any FS routes whose metric is less than or equal to the product of the variance by the FD are considered to be equal routes and can be placed into the routing table, up to and including the number of routes defined by the maximum-paths command.

The following list summarizes the key points to know about variance:

* The variance is multiplied by the current FD (the metric of the best route to reach a subnet).

* Any FS routes whose calculated metric is less than or equal to the product of variance and FD are added to the IP routing table, assuming that the maximum-paths setting allows more routes.

* Routes that are neither successor nor feasible successor routes can never be added to the IP routing table, regardless of the variance setting.
