I have this on my firewall facing the internet:


router eigrp 120

no auto-summary

network 192.168.10.0.0 255.255.255.0

redistribute static metric 1000000 1 255 1 1500


and that on my switch behind the firewall:


router eigrp 120

network 192.168.10.0 0.0.0.255

eigrp stub connected summary


i just got this config from an old employee.  can someone explain this to me?

I am seeing that the default gateway on the switch is the firewall and is learned from eigrp, what does this mean :


redistribute static metric 1000000 1 255 1 1500

The 'redistribute static metric 1000000 1 255 1 1500' command is redistribute static routes into EIGRP with the default metric values of 1000000 1 255 1 1500. This Reads from left to right, Bandwidth, Delay, Reliability, Load, and MTU. 1000000 is the Bandwidth value, 1 is the delay value (1-255) so a delay is 1 is the least amount of delay you can have, 255 is the value of Reliability (1-255) so 1 is the best Reliability you can have, 1 is the load, (1-255), this means you have little load on this metric, 1500 is the MTU value.


The switch behidn the firewall is oboviously a L3 switch, and is setup as a EIGRP Stub Router, which is receving routes, but only advertising connected and summary routes to it's EIGRP neighbors within it's AS.


I hope that helped.
