Понадобилась абонентам выдавать подсети. Для этого при авторизации сессии передаю по протоколу radius циске атрибут Framed-Route="192.168.101.0/24 192.168.193.226", где 192.168.193.226 - адрес абонента, 192.168.101.0/24 - адрес сети абонента. После установки сессии имеем:

 

sh ip route static 
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
      D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area 
      N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
      E1 - OSPF external type 1, E2 - OSPF external type 2
      i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS leve18l-2
      ia - IS-IS inter area, * - candidate default, U - per-user static route
      o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
      + - replicated route, % - next hop override

Gateway of last resort is 10.242.27.254 to network 0.0.0.0
...
S        192.168.193.226 is directly connected, GigabitEthernet0/0.100
U     192.168.101.0/24 [1/0] via 192.168.193.226

 

Адрес 192.168.193.226 пингуется, но с циски сеть 192.168.101.0/24 недоступна. При попытке пропинговать с циски хосты сети 192.168.101.0/24 пакеты уходят на абонентский роутер, хосты отвечают, icmp reply уходят на циску, но та их обрасывает. Блокируется весь входящий трафик на циску из сети 192.168.101.0/24.
