HI All,

I have a Cisco 1721 Router that has one ADSL WIC and one Ethernet port, my ISP has given me a range of addresses (28BIT SUBNET) that said the configeration is such that when the ADSL WIC dials up it assigns my dialer interface an IP address within then range given to me by the ISP. I know I need to set-up bridging but do not know where to start.

so ADSL WIC when dialed up gets an IP address of *.*.17.65/28 my range is *.*.17.64/28 so I have given the ethernet interface an IP address of *.*.17.77/28

Is there anyone out there who can help with the bridging set-up


thanks

if you want to bridge between the WAN and LAN interfaces you could use a config similar to this.

no ip routing (need to turn it off in this example)

int f0/0
ip addr
bridge-group 1

int s0/0 (your ADSL interface)
bridge-group 1

bridge-group 1 protocol ieee

This puts all the interfaces into the same Ip network, and uses transparent bridging.


 
Thanks that worked a treat
