remote offices dail in to center,the six telephone lines of center have been configured to a hunt group.how can I do to configure router of center and remote offices?
03-19-2003 07:31 PM
When the central site has 6 numbers in a hunt group means the remote routers will have to dial the same number...suppose the first line is busy with a modem call then the telephone switch should route the call to the next modem line automatically....there is no special configurations needed on the central side router for this to happen.
For the central site the config should be as below:
http://www.cisco.com/warp/public/793/access_dial/pppdialup.html
For the remote side to callout, use below config...instead of aux port in the sample config, you can configure the appropriate port / line that the modem is connected on.

Mak ,thanks for your help.
when remote client dial in,the center site router will assign a ip address to remote cilent.but for sercury,both cannot use dynamic routing protocal,how can I configure route?
Thanks,Ricky.

If you cannot use dynamic routing protocols then will need to use static routes on all the routers...depending on how your overall network toplogy is, will need to add lots of static route commands.
Just curious, did you mean security reasons for not using dynamic routing protocols?

using static route,I must special the next-hop address,but when dial in ,the center site will dynamic assign a address to remonte clients,next time ,the address may be different.so I cannot configure it.maybe I can use default route,but remote clients not only connet to center site,but connet to other sites.
Can I still use default route?
If using dynamic routing protocols,the updating route will announce internal networks.so I think it is not security.
Thanks,Ricky

Using dialer profiles can create dialer interfaces on the central site for each remote site dialing in & assign static ip addresses to the remote dialin.

The static routes can also be pointed to the routers interface (outgoing), eg,
ip route x.x.x.x y.y.y.y dialer1
If you have a big network with the requirement to connect between various sites then using a dynamic routing protocol with be the best way.
Thanks, Mak.

AS primary line down,remote router can diall in and connect to center site.
but "ping 9.148.47.254",time out.
if I remove "ip inside nat,ip outside nat" from remote router,"ping 9.148.47.254",reply from.....
Can interface of dailer support NAT?If yes,how to configure it?
thanks Ricky
