Re: ❓ what's the best solution for OSPF and PPPoE service

In general, I'd recommend as best practices that you never use redistribute connected unless it's just unavoidable for some reason (I can't imagine many such scenarios), and don't redistribute static routes except at the very edge of your OSPF domain - on access routers mostly - and in those router...

Re: ospf summarization help

But how many OSPF routes in the routing table? My thought is you probably do not need so many areas, especially if you only have a couple hundred routes. More areas used to be needed with older routers, but those were recommendations based on 1990's or early 2000's routers. Sorry I missed that you ...

Re: Renew IP address of PPPoE client

I mean if you use /24 for pppoe pool divide it to /25 and create 2 x ip pool and use next pool option

here is an example
/ip pool
add name=PPPoE_Pool-1 ranges=100.64.16.0/25  next-pool=pool1
add name=pppoe_pool-2 ranges=100.64.16.128/25

HI! if you're trying to summarize routes using OSPF, then the PPPoE server will be the ABR (area border router) or ASBR; but you'll need to standardize your subnets, as example PPPoE 1 will have clients at only one range (a.e. 172.16.0.0/24); then you can do a redistribute connected and the add a s...
