Dear Group,
One of the most often discussed problems here is redundancy and what to do
about it.
I'm reading up on HSRP and while talking to a buddy - he stated that HSRP
does not support L2TP and that they were engaged with Cisco to get a version
of IOS that supports that. However that endeavour has somewhat cooled and
they're still grappling for a solution.
So, I'm beginning to look into HSRP and I'm wondering, if your network
already has redundant paths, what do other people do to protect their
dial-in users? Specifically if they are using a VPN technology. From the
sounds of it they want the same type of fail-over you'd expect in LAN, the
user should hardly notice it.
I'm curious as to how far you could take this protection as to my mind
anything that uses a phone line has any number of things that can wrong. I
think they are using a 5300. If the user terminates his call at the 5300
and the 5300 dies - well.... doesn't that take the internal modems with it?
Just what kind of redundancy can you get for a circuit like this?
Using any other kind of access, the modem dies and you're toast. Time for a
new modem or dial into a new line. I've seen a device that recognizes that
after a set number of rings - it considers the modem dead and takes that
line out of service. If you're using a pool then the next caller gets the
next line, however the caller that called in when it is dead is sort of the
guinea pig and he must hang up and dial in again to get a new line.
Anyone out there looked at anything like this? It's caught my interest
somewhat.
