Which area for PPPoE Server ?

Sun Oct 14, 2018 8:32 pm

Hi All,
I have just passing from bridged network to a fully routed network with ospf, I keeped pppoe server's on backbone area... should i use stub area for pppoe server's ? or they should in backbone are ? I use backbone area for pppoe_server ip and loopback ip. and Im using that command below for customer's pppoe_client ip range on server;
/routing ospf area add area-id=0.0.0.1 name=pppoe1 type=stub  inject-summary-lsas=yes
/routing ospf network add area=pppoe1 network=100.64.15.0/24
/routing ospf area range add advertise=yes area=pppoe1 range=100.64.15.0/24
/routing ospf interface add interface=all passive=yes
Thanks.

It can be done on ASBR router in order to realease cusomer's ppp tunnels traffic from your AS right to the Internet.

Yes, you should use a stub area for PPPoE. We have multiple concentrators in different places and so we use a stub area on each, we have the router ID double as the area ID for the stub area so that we don't need to separately track the stub areas. Do not put the customers in the backbone or you will get customer /32's sent as LSA's creating too many routing updates on connection or disconnection of customers. Having the loopback and other non-PPPoE things in the backbone area on the same router is fine.

Hi mducharme,
I will create rules for put the customers to stub area as below, I use this on pppoe_server's
/routing ospf area add area-id=0.0.0.1 name=pppoe1 type=stub  inject-summary-lsas=yes
/routing ospf network add area=pppoe1 network=100.64.15.0/24
/routing ospf area range add advertise=yes area=pppoe1 range=100.64.15.0/24
/routing ospf interface add interface=all passive=yes
Now ppoe_server's on backbone area, and you suggest me that I should keep them at stub area, am I true ? I will try to draw some diagram to show better

Thanks

Do you know what a difference between default and stub and totally stubby area? Which types goes through areas,which no? and whats the goal?
The answer will be dependent what you want to do

How you mean "and I sent ppppoe connections to pppoe server over eoip."

just keep in mind all non backbone MUST be connected to backbone area, otherwise you have to play with virtual link.

On Ap's I create eoip tunnel betwen AP and pppoe_server and I sent customers pppoe_client connections over this eoip to pppoe_server

all of them as like this

Of course you can if it's stub. If it's has no exit to any other places except backbone. Also if area1 has only one uplink, you can use totally stub area, to loose all specific routes.

thanks Anumrak,
how many router can be one area in ospf, is there any limitation ? cause I changed this area1 to stup and there is nearly 80 router.
and pppoe_server should be stub area also ? should i create new stub area at backbone roter and put the pppoe_server to this area ?

Thanks

"should i create new stub area at backbone roter and put the pppoe_server to this area" - yes, only because of saving routers energy for recalculations of SPF.

Official Cisco limitation is 100 routers, but in reality I saw not more that tens.

Thanks for your help;

I will create new pppoe_serever and put it new are and test to see results, cause I have 5 pppoe_server on system and all of them in backbone area.
Official Cisco limitation is 100 routers, but in reality I saw not more that tens.
you mean that, its not stable when pass 10 routers in one area ? I think I have more than 70 router in one area(prefer to use totally stub).
I will re configure my network if that make me problem.

thanks again for sharing your experience....

It depends how often your network changing thier routes and links. If pretty often - 70 routers is bad idea. If not often at all - let it be. Also you have to assign DR and BDR in your area manually as most "strongest" routers.

routes not changing on this routers to much but I will divide them to multi area at backbone router as your suggest, if you look the diagram that I shared only powerbox as ospf router. I did not set ospf on other SXT's.. if we calculate routers which are installed ospf on them maximum 70 on one totally stub area, I did not install OSPF to all others are AP(SXT)
Also you have to assign DR and BDR in your area manually as most "strongest" routers.
on bgp router I use nat all ip's and ospf also intalled on it. using static route on it may better but after bgp router I have two another backbone router and some ip's that assigned by radius for customer client ip's may at different locations at different times. can I route Ip to two backbone routes's at same time. Likle;
add distance=1 dst-address=10.10.0.0/24 gateway=10.10.10.14,10.10.10.222

Yes, if they are reachable as a next-hop.

What you wrote here is callled load balancing which is default setting of OSPF.(EIGRP can do it with unequal bandwidth links with 3 and more directions :))

I divided area1 which is had 170 device and more than 70 router ospf installed. to 4 different area but now I faced with new problem :=) I used area ranges for summarize network.. and now I couldn't find how I will summarize them again, because I use 3 diffident /24 ip range and all of them at different areas.

Choose a good place for ABR and do summarization.
