route-map definition

[Mary]

in the configuration file,

 route-map test permit 10

match metric 11+-10

I want to know does this match mertic from 1 to 21? if I use match metric 10+-11, is the same result or different? thanks

match metric 11+-10 ....it will give you a range deviation value  -20  to + 42 any metric matched with that value will be redistributed in the route-map if that's the way your setting it up

[Mary]

I'm quite confused, how is -20 and 42 derived? can you show the calculation.

what's the range of the match metric 10+-11, can you also show the calculation, we have two interface, one is using ospf, the other is using eigrp, now we want to redistribute ospf to eigrp and apply route-map

[Mark Malone]

when you go to create the route-map using the +- it gives you an example of how it calculates, I worked it out from that based on the numbers you provided

(config-route-map)#match metric 1 +- ?
  <1-4294967295>  deviation value, 500 +- 10 creates the range 490 - 510

[Mary]

match metric 11+-10, range is 1 (11-10) to 21(11+10)

match meric  10+-11, range is -1 to 21

can we see from show route-map command or there is other command to show the result?
