IP addresses cannot be used as the EAP identity. Query-identity keyword is not configured and the FlexVPN client’s IKEv2 identity is an IPv4 or IPv6 address, the session is terminated because Query-identity keyword is configured, the FlexVPN server queries the EAP identity from the client otherwise, the FlexVPN client’s IKEv2 FlexVPN clients authenticate using EAP by skipping the AUTH payload in the IKE_AUTH The FlexVPN server is configured to authenticate FlexVPN clients that use EAP by configuring theĪuthentication remote eap command in IKEv2 profile configuration mode. While a FlexVPN client authenticates the FlexVPN client using EAP, the FlexVPN server must authenticated by using certificates. The backend EAP server is typically a RADIUS The FlexVPN server supports peer authentication using the Extensible Authentication protocol (EAP) and acts as a pass-throughĪuthenticator relaying EAP messages between the client and the backend EAP server. The IPSec sessions during ISSU is obvious in this case. Or interfaces that have keepalive enabled, or where there is an auto trigger for an IPSec session. Shutdown in the case of interfaces that may initiate a tunnel setup, such as a routing protocol initiating a tunnel setup, That there are no half-open or half-established IPSec tunnels present before performing ISSU. Terminate all existing IPSec sessions or tunnels prior to the operation and reestablish them post ISSU. Before performing an ISSU, you must explicitly

The Cisco ASR 1000 Series Router does not support stateful ISSU for IPSec sessions. Traffic disruption might happen over the IPSec sessions for the duration of the switchover, until The IPSec sessions will go down on initiation of the switchover, but will come back up when the new RP becomes active. The Cisco ASR 1000 Series Router currently does not support Stateful Switchover (SSO) IPSec sessions on Route Processors (RPs). Traffic disruption might happen over the IPSec sessions in such cases for the That have a single ESP after an ESP reload. You may need to explicitly reestablish IPSec sessions to work around this issue for systems The peer router drops packets that do not have DuringĮSP switchover, all IPSec sessions will stay up and no user intervention is needed to maintain IPSec sessions.įor an ESP reload (no standby ESP), the SA sequence number restarts from 0. The Cisco ASR 1000 Series Routers support stateful IPSec sessions on Embedded Services Processor (ESP) switchover. The vrf forwarding vrf-name command to define the IVRF of the tunnel interface, where the vrf-name argument is defined using the vrf definition command with IPv4 and IPv6 address families inside the definition. The ip vrf forwarding command to configure an Inside VPN routing and forwarding (IVRF) instance because this is not a valid configuration. When configuring a dual-stack tunnel interface in a VPN routing and forwarding (VRF)-aware IPsec scenario, you cannot use An account on is not required.ĭual-Stack Tunnel Interface and VRF-Aware IPsec
