Static Route with Tag number

Answered Question
Oct 18th, 2007

Hi,

Does this command

ip route 10.64.0.0 255.240.0.0 192.168.50.2 20 tag 102

overwrites this command

ip route 10.64.0.0 255.240.0.0 192.168.50.2 10 tag 101

? or vise versa?

Thanks in advance

Routes must have different next-hop in order to be different, otherwise they're considered as the same route so second command overwrites first one.

Hi,

The tag is use to reference a route in a route map for making policy decision.

You have two floating static route diferrentiated by their administrative distance of 10 and 20. I don't think the routes overwrite each other by the tag.

Hi Dandy,

Yes, this is right. But, why when i apply these two static routes at Cisco 6509 switch, the last one applied is the one appeared at the show running?

Thanks

Hi,

I didn't noticed the next hop which is the same. The second one will overwrite the first one with or without tag.
