Hello.
Here is interface config:
interface TenGigabitEthernet0/1/0.199
encapsulation dot1Q 199
ip address 100.65.0.1 255.255.0.0
ip nat inside
ipv6 address ISP 0:0:0:199::/64 eui-64
ipv6 enable
service-policy type control Captive
ip subscriber l2-connected
initiator unclassified mac-address
Problem is that there is no NA as default router is received on client host. So it cannot initiate connection to Internet and trigger ISG session.
Instead it gets strange ISP:ISP:2::/60 RA, while there is no such route on the router, but ISP:ISP:2::/48 to Null0.
My platform is ASR 1002-X, asr1002x-universalk9.03.13.02.S.154-3.S2-ext.SPA.bin
If i remove "ip subscriber l2-connected" then it starts working and client receives "neighbor advertisement, length 32, tgt is ISP:ISP:0:199:8af0:31ff:feac:8c10, Flags [router, override]"
What do i do wrong?
