IPv6 over DMVPN |
12.4(20)T |
The DMVPN feature allows users to better scale large and small IPsec Virtual Private Networks (VPNs) by combining generic routing encapsulation (GRE) tunnels, IP security (IPsec) encryption, and the Next Hop Resolution Protocol (NHRP). In Dynamic Multipoint Virtual Private Network (DMVPN) for IPv6, the public network (the Internet) is a pure IPv4 network, and the private network (the intranet) is IPv6 capable. The following commands were introduced or modified: clear dmvpn session, clear ipv6 nhrp, crypto ipsec profile, debug dmvpn, debug dmvpn condition, debug nhrp condition, debug nhrp error, ipv6 nhrp authentication, ipv6 nhrp holdtime, ipv6 nhrp interest, ipv6 nhrp map, ipv6 nhrp map multicast, ipv6 nhrp map multicast dynamic, ipv6 nhrp max-send, ipv6 nhrp network-id, ipv6 nhrp nhs, ipv6 nhrp record, ipv6 nhrp redirect, ipv6 nhrp registration, ipv6 nhrp responder, ipv6 nhrp server-only, ipv6 nhrp shortcut, ipv6 nhrp trigger-svc, ipv6 nhrp use, set pfs, set security-association lifetime, set transform-set, show dmvpn, show ipv6 nhrp, show ipv6 nhrp multicast, show ipv6 nhrp nhs, show ipv6 nhrp summary, show ipv6 nhrp traffic. |
