He said the router is acting as a translation (sic) bridge. So the router (bridge) address does not come into play. The router (bridge) translates the non-canonical TR address to a canonical Ethernet address. The bridge reverses the bits in each byte of the address.
We have had many discussions on how to do this. It's as simple as writing your name backwards. For example, let's say one byte was 4A in hex. Put that in binary, one digit at a time. 4 A 0100 1010 Now write it backwards: 0101 0010 Put it back in hex: 52 If this seems mysterious or difficult to apply in a generic fashion to any hex representation of a byte, then it's not time yet to go for CCIE.
