Cisco 851 Wired configured for Verizon FIOS

By metech00 ·
I've poured through the postings and have found quite a few scripts to configure a bunch of Cisco device with wireless settings and have tried to modify them to fit my wired configuration but with no luck.

Does anyone have a straight forward CLI script to configure a Cisco 851 wired router for Verizon FIOS?

Also, I'd like to know how to set it back to factory so I can use SDM and SDM express again *sigh*

Set to default

by zreisman In reply to Cisco 851 Wired configure ...

To set back to defaults there is a recessed button on the back. Push and hold with a pencil for about 10 seconds until you see the lights go off and start to come back on. Once reset it is set with a 10.x IP. It has dhcp enable by default so just release and renew your IP address or restart your computer and you'll be able to run the SDM express.

FIOS interfaces for Cisco 871

by AWhiteKISA In reply to Cisco 851 Wired configure ...

I have a Cisco 871 connected to my FIOS and it works like a charm. Here are the interfaces relevent to connecting it to the FIOS network.

My FIOS wan connection is on Fast ethernet port #4 on my 871.

!Configure the ethernet port
interface FastEthernet4
description $ETH-WAN$
no ip address
ip mask-reply
ip directed-broadcast
ip route-cache flow
speed auto
pppoe enable group global
pppoe-client dial-pool-number 1
!Configure the dialer interface needed to log into Verizon
interface Dialer0
description FIOS Dialer Int
ip address negotiated
ip access-group (YourAccessGroup#)
no ip redirects
no ip unreachables
no ip proxy-arp
! MTU cannot be larger than 1492 but a little smaller helps some web sites load faster
ip mtu 1400
ip nat outside
ip virtual-reassembly
encapsulation ppp
ip route-cache flow
dialer pool 1
dialer-group 1
!this is where your router will log into the FIOS network
ppp authentication pap callin
ppp pap sent-username (YourFIOSusername) password (YourFIOSAccountPW)
ppp ipcp dns request
ppp ipcp address accept
!Routes through the FIOS interface
ip route Dialer0 permanent
!Nat parameters and interface
ip nat inside source route-map SDM_RMAP_1 interface Dialer0 overload
route-map SDM_RMAP_1 permit 1
match ip address (YourACL#)

I hope this helps.

Verizon FiOS PPPoE

by alston In reply to FIOS interfaces for Cisco ...

I have a Cisco871 and will like to use FiOS PPPoE. Verizon FiOS gave me a WAN subnet which I think is incorrect They call it 5 static IPs. I don't like the I have to configure the router for it to work. What support contact # you called to get a FiOS PPPoE account? I'm trying to get one, but no one at Verizon FiOS Business could connect me to the right dept.

Fios has flavors

by Lwood In reply to FIOS interfaces for Cisco ...

Yours could be PPOE configuration but probably not - most FIOS connections are now Fiber to your house and then ethernet into your residence. I have a 870w engineered over a FIOS ethernet connection whereas the lan network and wireless network are bridged - additionally, I have a guest wlan for visiting friends, etc. It is a sweet setup! Contact me if you think you need the eth config and I will forward a script to burn to your router - Also, the easiest way to get to factory config is: at a command prompt type: erase startup ...after it finishes type in: reload - the router will reboot to factory defaults clean as can be.
