Hi,


We are receiving prefixes from our partners with multiple communities set which is specific to the locations. Say for exampls


xxxx:xxaa

xxxx:xxab

xxxx:xxac


Similar to the above one.


I want to set the preference high for all the communities xxxx:xx-- the last 2 digits can be any value.

The last 2 digits are actually dont care bits.


One way is to define the community list with as many entries as the communities that i m receiving from the partner and set the local preference with route map. But the problem here is i m receiving around 50 communities from the same partner.


I want to add a single entry in community list with last 2 digits being dont care.


somthing like


ip community-list test permit xxxx:xx**


Is it any way I can achieve this.



thanks

Arun Kumar
