DLSW Icanreach

There is a lot of confusion about running dlsw+ between two routers.

For example, If a there is a peer relationship between r1 and r2.

r1 config,

dlsw local-peer peer-id 1.1.1.1

dlsw remote-peer 0 tcp 2.2.2.2

r2 config,

dlsw local-peer peer-id 2.2.2.2

dlsw remot-peer 0 tcp 1.1.1.1

both r1 and r2 have ethernet host.

host on r1's mac-address is 1234.4321.0001

Now I want r2 to reach an ethernet host only.

my statement would be on r1

dlsw icannreach mac-address 1234.4321.0001 mask ffff.ffff.ffff

dlsw icanreach mac-exclusive.

Is the above statement correct? or will I have to do a bit-swapping since the ehternet only understands cononial format, and dlsw understands non-cononial format, then it should be like that

dlsw icanreach mac-address 483c.c383.0080 mask ffff.ffff.ffff

dlsw icanreach mac-exculsive.

Please confirm when to do bitswapping in pure ethernet enviroment.

Thanks,

Re: DLSW Icanreach

The first one is correct.

You dont need to swap the mac-address bits. You can give them as it is. Once you give a icanreach command, give a show dlsw capabilities command on the remote, and see whether this mac address is listed. I hope that does answer your question.

Re: DLSW Icanreach

dlsw should do the bit swapping for you.

heres a link on some other stuff for this protocol
