redistribute external route

Fri Mar 04, 2022 11:57 am

Hi,

I have a problem with unreachable route when using area summarization. I either have summarization working, but external route is unreachable, or the route is reachable, but summarization not working. In version 6, both working with no problem. My setup is simple: I have clients connecting to NAS (CCR1009) via PPPOE and this NAS is connected to cisco router via OSPF. Since there are thousands of people connecting this way and getting IP from /20 pool, I need to summarize it.

Config is:
/routing bgp template
set default disabled=no output.network=bgp-networks .redistribute=static,vpn,dhcp
/routing ospf instance
add name=default-v2 originate-default=never redistribute=connected,static,vpn,dhcp,modem router-id=main
/routing ospf area
add area-id=0.0.0.87 default-cost=1 instance=default-v2 name=area1-v2 no-summaries nssa-translator=no type=nssa
/routing ospf interface-template
add area=area1-v2 networks=x.x.x.x/28 priority=1 type=broadcast
add area=area1-v2 networks=10.79.240.0/20 priority=1 type=ptp

x.x.x.x/28 is just OSPF from NAS to Cisco
10.79.240.0/20 is the network I want to summarize

One think I noticed is, that the route I need to have reachable is DAy in routing table. In version 6, it was DAS.

Is this a bug or am I doing something wrong?

Thanks

how are you sumarizing? with
/ip ospf area range
??

I am assuming your cisco is the ABR?


You have left out so much information it's impossible to help at this point.
