Re: interesting traffic?
Yes what i think is that you have forgot the 'dialer-group 1' command on the dialer interface and 'dialer-list 1 protocol ip permit' or 'dialer-list 1 protocol ip list 1' where list 1 is the access list you define to generate the interesting traffic.

Re: Function of IP HELPER ADDRESS & IP DIRECTED BROADCAST ?
Router by-default doesn't forward the broadcast storm. So any application that requires broadcast to be forwarded to another subnet wiould be blocked by the router. Taking the example of DHCP Server & Client. A DHCP Client machine on bootup sends broadcast in search of a BBOTP Server. As long as this server is in the same subnet, an IP address will be automatically assigned to that machine. However if the DHCP server is on another subnet, this broadcast will no be forwarded to that subnet (The behaviour of a Router) unless we specify the IP HELPER-ADDRESS w.x.y.z command on the interface that is recieving the broadcast (i.e. the interface with subnet of client's machine). this command actually converts the broadcast to a unicast address, where the unicast address is specified by the IP address of the DHCP server specified in the Helper-address command. As long as there is only one DHCP server you require nothing else (i.e no requirement for IP DIRECTED-BROADCAST command) but if there are multiple dhcp servers on the same subnet you have to define the directed broadcast address in the ip helper-address command. Eg if the network is 10.1.1.0/24 then the directed-broadcast address would be 10.1.1.255. In this case you have to define ip directed-broadcast command on the interfaces.

Hi All, I just wanna know if 1600 routers support BGP. If yes, then which IOS version and what are the memory requirements. I've heard that BGP is rather a platform dependent routing protocol. Is this true?

Re: Reverse Telnet
Well you can connect async modems at the async interfaces, configure the lines as 'modem inout' , 'transport input all' 'modem autoconfigure type xxx' and etc. Also create a loopback interface or keep the Ethernet interface UP and then telnet it to this IP address with port no as (2000 + x) where x is the line no.

Re: IP Helper-address questions [7:247]
Actually, the IP helper command is placed on the interface that is recieving the broadcasts. Now you have to decide which router is supposed to recieve the broadcasts. But in usual case, Clients usually try to communcate with the PDC for authentication and other stuffs. So, i think it would work to configure ip helper-address w.x.y.z on the ethernet interface of router 1 only (where w.x.y.z is the ip address of your PDC, but if you have multiple PDCs then you have to give the directed-broadcast address and also have to use ip directed-broadcast command).

Re: IP Helper-address questions [7:247]
Yes, The DHCP server will check the IP address of the interface on which you have configured the IP Helper address command. So make pools on the DHCP server accordingly. eg: Router's interface 192.168.1.1/16 Server' pool 192.168.0.1-192.168.255.254 wil work. Muhammad Khalilullah CCNP, MCSE --- "Jason J.
