Strange question here,

I'd like to maintain PPP timeouts based on LCP layer Echo rather than
relying on "ppp idle timeout" which seems to operate up in the IPCP.

I've done this with other vendor's kit before, but , for the life of me
I can't seem to find any documentation for doing this on cisco
virtual-template.

I'd like to be able to configure a timeout based on this.

Any assistance appreciated,

Kind Regards,

Well, just enable keepalive with the appropriate timer on the
vtemplate.. the regular keepalive mechanisms applies here, three
consecutive missed keepalives tears down LCP ..

Actually, the default is 5 missed keepalives, but one can tune this as
he wishes:

c3620(config-if)#keepalive ?
<0-32767> Keepalive period (default 10 seconds)
<cr>

c3620(config-if)#keepalive 10 ?
<1-255> Keepalive retries
<cr>
