Configuring Transparent Bridging

Transparent and SRT Bridging Configuration Examples

However, the following configuration might work initially but will eventually fail. The failure occurs because the configuration does not allow for an ARP broadcast with a destination address of FFFF.FFFF.FFFF, even though the destination address on the output interface is correct:

access-list 700 permit 0260.8c34.0864 0000.0000.0000 access-list 700 deny 0000.0000.0000 FFFF.FFFF.FFFF interface ethernet 0

bridge-group 1 output-address-list 700

The correct access list would be as follows:

access-list 700

permit 0260.8c34.0864

0000.0000.0000

access-list

700

permit FFFF.FFFF.FFFF

0000.0000.0000

access-list

700

deny 0000.0000.0000

FFFF.FFFF.FFFF

interface ethernet 0
