BFD for IPv6 interfaces is supported only the 7210 SAS-Mxp.
On the 7210 SAS-Mxp, BFD IPv6 processing is supported in hardware, enabling faster detection (the minimum timer supported is 10 ms). Hardware-based BFD sessions are supported only for an IP interface configured on a port.
For IP interfaces using the IPv6 addresses of interfaces configured over LAG and for BFD sessions using system IPv6 addresses or loopback IPv6 addresses, CPM CPU-based sessions are supported with a minimum timer of 100 ms.
BFD IPv6 is supported on the 7210 SAS-Mxp in VPRN, IES, and R-VPLS services and network IPv6 interfaces. The following table indicates the support matrix for BFD IPv6 on the 7210 SAS-Mxp.
| Service | Routing protocol | Hardware or central CPU-based BFD IPv6 session | IP address used by BFD IPv6 session | ||
