REP on Wireless

[gjelke]

I have a client needing to have a segment of the REP ring being wireless p2p link. Perhaps even more than one.

I can find documentation of what is supported, is it safe to assume that all other variations are then not supported?

Supported Platforms

• Desktop Switching Business Unit (DSBU) Metro Switches (3750ME and ME3400) Release 12.2(40)SE and later
• Cisco Catalyst 4500 Series Switch Release 12.2(44)SG and later
• Cisco Catalyst 6500 Series Switch Starting in Whitney2 (12.2SXI)
• Cisco Catalyst 7600 Series Router Starting in Cobra (12.2SRC)

 of course as it is a L2 protocol, it might work over wireless links that transparently forward L2 packets.
but  I would read info in above document as not supported on other devices than above mentioned

added: more supported devices

Thanks, this is the documents that I had previously found. I was hoping where buried within Cisco's documentation mountain there might have been a tech note or something that suggests that it can be supported in these circumstances.

that would be correct, as far as I know Resilient Ethernet Protocol (REP) is not natively designed to run directly over standard Wi-Fi wireless links

[pieterh]

redundancy proticols are there to provide redundancy en improve availability of the network
as such a wireless link is not the best solution (unless Cisco's recently introduced URWB)

but...., if you cannot use a wired link it can still be the best option in this environment
as said before  it probably will work, but i doubt it is documented in any support document by Cisco

and then you want to use multiple wireless segments in the ring.....?.....
-> try to avoid that,
    try to split this in multiple rings each with a single wireless segment

Thanks @pieterh , unfortunatly there will be more than one wireless segment due ot the nature of the topology of the physical environment.
