<p class="MsoNormal"><span style="font-size:12.0pt">The only reason that I’ve seen for people to do RTR over SSH is for older Cisco code that can’t source RTR traffic from a specific interface. If the RTR traffic is encapsulated in SSH, the older Cisco code
does allows sourcing that SSH client traffic from a specific interface. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt">We are not too concerned about protecting the confidentiality of the unencrypted RTR traffic with SSH tunneling since all of this traffic would be going across our own links. I guess if you have this concerned
about a monkey in the middle situation, then SSH tunneling might make sense. Other than that, SSH tunneling seems to introduce more issues than it solves.<o:p></o:p></span></p>
