We have to service elevators, campus emergency phones, and provide a means to allow departments to have at least one phone that will work in the event of a system outage (this will be their fax machines).<br><br>I've put some thought into it, but my networking skills aren't what they used to be. *sigh*<br><br>I've attached an image.<br><br>I'm thinking:<br><ul><li>installing two 3945s with switchport modules in them</li><li>create a VLAN on each router to be the HSRP active/standby interface - VLAN 101</li><li>assign two ports on each switch module to VLAN 101 and connect the routers to each other (two links for redundancy, port channel or whatever)</li><li>create two point to point routed VLANs for each VG224, on on router A for VG224 i/f 0, and one on router B for VG224 i/f 1</li><li>connect each router using routed VLANs to the campus network</li><li>create dial peers on router B to point to router A (HSRP Active) so that PSTN calls will be routed properly (and if there are any IP phones installed, or if the VG224 link to Router A is compromised)<br></li><li>use EIGRP magic to make things work<br></li></ul><br>Questions:<br><ul><li>Will the standby router become active if the other router is powered off? My main concern is whether the VLAN interface will be in an appropriate "up/up" mode</li><ul><li>this FAQ seems to say yes: http://www.cisco.com/en/US/tech/tk648/tk362/technologies_q_and_a_item09186a00800a9679.shtml#q1</li></ul><li>I'd like to also put dial peers on Router A pointing to Router B in the case that Router B becomes active for some reason. From a previous post, this should be OK, because H323 dialpeer loop prevention is on by default.</li></ul>In general, do you think this will work?<br><br>---<br>Lelio Fulgenzi, B.A.<br>Senior Analyst (CCS) * University of Guelph * Guelph, Ontario N1G 2W1<br>(519) 824-4120 x56354 (519) 767-1060 FAX (JNHN)<br>^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^<br>"Bad grammar makes me [sic]" - Tshirt<br><br></div></body></html>
