? about SXT and best current practice regarding ptp links

Having just received our first shipment of SXTs, I wanted to ask fellow MikroTik community members about their views of best current practices with regards to ptp links.

For example, beyond what Uldis has written about the SXT and ptp links, are you using bridging or routing?

If bridging, are you using MPLS?

If bridging and using MPLS and referring to

http://wiki.mikrotik.com/wiki/Transparently_Bridge_two_Networks_using_MPLS

can the IPs on the AP and station be on the same subnet as the LAN on either end of the link?

e.g., we typically assign a /29 for each link and use something like this (all infrastructure subnets are in RFC 1918 address space):

subnet addr 0 -
subnet addr 1 - gateway ethx at upstream pop
subnet addr 2 - reserved
subnet addr 3 - reserved
subnet addr 4 - near end of link (to be an SXT)
subnet addr 5 - far end of link (to be an SXT)
subnet addr 6 - ethy of MikroTik router/gateway at wi-pop
subnet addr 7 -

Is there a better way we should be using?

THANKS/ldv

a rural ISP who thinks Will Rogers was correct in his statement “We’re all ignorant, just about different things.”

What I did was put the desired subnet addresses on eth1 at each end of the link (for management purposes) and 172.31.0.1/30 on the wlan1 on the near end of the link and 172.31.0.2/30 on the wlan1 of the far end of the link.

Otherwise, the wiki page at http://wiki.mikrotik.com/wiki/Transparently_Bridge_two_Networks_using_MPLS was followed.

Seems to be working OK, but if you know of problems with that particular setup/configuration, I would appreciate a heads up.
