<p class=MsoNormal>Hi all,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><span lang=EN-US>The other day I was playing around a little
bit, and tried to create a L2 redundancy structure using MRP and VSRP. In
essence I’d like to create a MRP ring over 4 NetIron switches, and
connect a fifth box, some router to two of the four switches. In order to
provide a redundant connection between the switching platform and the router I’d
like to use VSRP, which according to the VSRP-chapter in the NetIron config
guide (5.1.00, sub-chapter “VSRP and Foundry MRP signaling”, figure
143-145) should be a piece of cake.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I created a VLAN tagged across the four
switches, gave it a MRP ring, created a topology group, created a second VLAN
(since this ring is usable for other stuff as well), and tried to put VSRP into
that VLAN, which failed:<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>

<p class=MsoNormal><span lang=EN-US>error - vlan VLAN: 2000 is member of
topology group.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Ok, so topology-groups and VSRP are not
compatible in that way. I tried to bless the MRP control VLAN with VSRP, which was
allowed by the CLI, but had different side effects:<o:p></o:p></span></p>
