Cisco Bug: CSCvt45502 - SDA Wireless: IPv6: Router Advertisement from incorrect VN/pool
Aug 21, 2020
- Cisco Aironet 1850 Series Access Points
Known Affected Releases
Symptom: SDA wireless deployment with IPv6. All users connect to the same SSID which is linked to a VN pool in DNAC by default. After Dot1X authentication, based on the user groups, ISE will authorize the user to his/her IP Pool/VN. ISE does override the VN correctly for the user based on the authorization policy and the user gets the IPv6 address correctly from DHCPv6 server from the correct VN/pool. The issue is that the edge switch also advertise RA (Router Advertisement) for default SSID pool/VN to the user. This causes a problem because the PC installs this incorrect route in the routing table and thinks that this default SSID pool/VN subnet is directly connected. The issue is not seen with wired IPv6 clients. Conditions: SDA wireless deployment with IPv6.
