Cisco 2811 with HWIC-4esw

Ok, heres my set up, i have 2 sites, one site has a 871 and the main site has a 2821.  They are currently connected via ipsec,  We just had p2p fiber 5x5 installed, however, there weren't enough ports on the 2821 to terminate that end, so I bought and installed a HWIC-4ESW.  I noticed I can't assign and IP address to any of the interfaces.  So my question is two fold, how can i terminate the p2p to this card? and Second, is it an all or nothing when it comes to using these ports, meaning the switch acts as its own independent switch?  the remote site will get internet and everything over this pipe.

HI,

you need to configure equal load balancing with EIGRP:

This is kind of a odd way of doing it but have don this in laps. If you create a vlan interface and assign the vlan the IP you want use then assign the vlan to the port. Kind of weird but it has worked for me in lab scenerio.
jasonmichelAuthor Commented:
The vlans are what i have in mind, not sure why I need EIGRP for a p2p with only 2 routers, I've never worked with EIGRP, i'd be interested in learning it if it will help.  Will it work basically like  BGP, as i've used that in mpls environments where you just basically advertise the networks sitting behind the router?  but i still need to assign and ip to the interface that is terminating the fiber correct?  as these act as L2 interfaces will they allow me to add them to a vlan?

ok i created a vlan  assigned one of the ports to it and assigned an IP to the vlan of 10.1.20.1, the other side i will assign an ip to the vlan there of 10.1.20.2  now, getting eigrp set up and getting internet to go across that pipe, any help on config example?  would my current config help?
Nayyar HH (CCIE RS)Network ArchitectCommented:
A basic config between both sites would like this;
!
! Remote site
!
router eigrp 1
no auto-summary
eigrp router-id 10.1.20.2
eigrp stub connected
network 10.0.0.0


!
! Main site
!
router eigrp 100
no auto-summary
eigrp router-id 10.1.20.1
network 10.0.0.0
!
!
int vlan x
ip summary-address eigrp 100 0.0.0.0 0.0.0.0
!

Note: Main site advertises default route to remote site for Internet
jasonmichelAuthor Commented:
ip summary-address eigrp 100 0.0.0.0 0.0.0.0

is this the syntax to advertise the default route?  
Nayyar HH (CCIE RS)Network ArchitectCommented:
Yes thats right
jasonmichelAuthor Commented:
and because the routes are advertised, I won't need any ACL's for reverse path correct?
Nayyar HH (CCIE RS)Network ArchitectCommented:
You would usually use ACL along with distribute-list to control route propagation. I this scenario i dont think its needed.
chad_rCommented:
No need to run EIGRP unless you want to.  But, back to your first issue, did you enter the "no switchport" command on one of the interfaces?  Once you enter that, you should be able to assign an IP.  
jasonmichelAuthor Commented:
actually i tried that and said it couldn't be altered. That was the first thing i tried.  If i didn't do eigrp, what would you recommend?
chad_rCommented:
interesting, but if you have it working with an SVI, and all the remote site needs is connectivity to this 2821 and out, I would simply add a default route at the remote site.  If there are other subnets that need to be reached at the remote site, you would either need to add a static(s) on the hub site router, or if there is more than one or two, this is where you should consider running a routing protocol to simplify things.  

ip route 0.0.0.0 0.0.0.0 10.1.20.1 (that's the 2821, correct?)
jasonmichelAuthor Commented:
Yeah the remote site just needs internet and exchange behind the 2821.  So I can basically just add Acl to each router to allow that new vlan
jasonmichelAuthor Commented:
Ok i used the EIGRP configs and so far everything seems ok, i can ping back and forth to that interface, I still have the ipsec tunnel up so that leads me to my next question, i assume i delete the Ip nat inside/outside off the remote site, as well as remove the default static route for the old ISP?  I am attaching both configs if you guys can look and see if you find any gotcha's, as i said i can ping back and forth to the two eigrp interfaces, just want to make sure.  Thanks
