I've got a Cisco 891 and I'm trying to configure the thing to connect to a 4x1 fiber connection. I don't know much about PPPOE.
But my router decides it doesn't like that command. Apparently, selecting protocol pppoe is not an option.
l2tp Use L2TP
Which based on the input from the previous line, it doesn't look like router supports pppoe.
I'm using C890-UNIVERSALK9-M, version 15.2(2)T
Any ideas why the command won't work?
After about 2 hours, myself and another technician got it working. The document works, I was just following the wrong portion of it.
Jump to the section "configure fast ethernet wan interfaces" and "configure the dialer interface"
chap hostname also turned out to be what the vendor called "user name".
Also, don't forget to move any ACLs, vpn maps, and anything else you may normally configure to the dialer interface as opposed to the normal wan interface.
Also, don't forget to make sure NAT overload is moved to the dialer interface as well.
Do your router able to ping to internet address like 22.214.171.124? Mine unable. Please help me with your full configuration please, I also have trouble about selecting protocol pppoe is not an option
There are a number of reasons a router can't ping 126.96.36.199. It depends on whether you have ACLs set up, NAT correctly configured, PPOE running properly, and a number of other issues.
With the setup I have, yes I'm capable of pinging 188.8.131.52.
Within my inbound acl I have a
permit icmp any any echo-reply
And that allows ping responses.
Once again, follow the Cisco tech document and skip down to "Configure Fast Ethernet WAN interfaces" and all should be good.
I did have to add
ip mtu 1454
ip tcp adjust-mss 1452
to the dialer interface to get https sites to work, but that might not be required in your situation.
The second part of that is that PPPOE is just a slightly different version of PPPOE. So you don't select PPPOE, you select PPP by using
on the dialer interface you set up.
