Friends,
Could any one will give clear idea what exactly means Widlcards (Route and translation patterns) and wildcard mask (Subnettings).
Thanks for your advance responce

Wildcard is any digits, which on Cisco CUCM is indicated by X chanracterm and on voice GW is . (dot). This matches any digit 0-9, #,*.

Hi Abhilash,
This wildcard is deducted by inversing a subnet mask.
On Cisco router, wildcard subnet mask is used in the following occasion
* Defining subnet in ACL
* Defining subnet member in OSPF area
For those who just learn networking, wildcard subnet mask is new and probably looks confusing. Don't worry, there is easier way to understand it.
Background Theory
For example, let's say you have the following subnet.
192.168.24.0/24
or 192.168.24.0 with 255.255.255.0 subnet mask
The binary format of the subnet mask is the following
11111111.11111111.11111111.00000000
In binary arithmetics, inverse a number means "flipping" one state to the other (i.e. from "on" to "off", from "0" to "1").
The inverse of the subnet mask in binary format is then the following
00000000.00000000.00000000.11111111
In decimal format, the inverse subnet mask looks like this
0.0.0.255

We appreciate you for immediate response; if it possible could you please give explanation about Wild card mask in the network subnetting.

Leosalcie,
A very good explanation witha perfect example and an apt explanation. so Wild card mask tells the number host in a subnet can we tell like this. Please try to modify if my understanding is wrong.
Thank you,
Abhilash
