CSCum98092 - MS-to-MS traffic for Ipsec
Feature Changes
MS-to-MS traffic for IPSec
When ACL includes a destination “any”and IPSec is used in the communication, then all packets are sent to the remote
IPSec peer through a tunnel, even when the subscriber is in the same IP pool. Some IPSec gateways cannot handle the
returning packets from the tunnel. This enhancement allows the routing packets within the system.
IPSec peer through a tunnel, even when the subscriber is in the same IP pool. Some IPSec gateways cannot handle the
returning packets from the tunnel. This enhancement allows the routing packets within the system.
Hence, with this enhancement, for any mobile to mobile communication the following options are possible:
Local routing within the node is possible and there is no need to send traffic out of the node for re-routing back.
Forced routing outside GGSN such as IPSec tunnel and next-hop is also possible.
Both options are configurable and available for all outside interface type such as nexthop, VLAN, MPLS, GRE tunnel,
IPSec tunnel, GRE over IPSec, and so on.
IPSec tunnel, GRE over IPSec, and so on.
Previous Behavior:
Packets are forced into the tunnel.
By default,
ip guarantee framed route local switching
has been enabled for VPN and VRF level.
New Behavior:
Packets are routed to connected subnets internally or can be routed into the tunnel if the option is configured.
By default,
ip guarantee framed route local switching
has been disabled at both VPN and VRF
level. When you change the value at VPN level, all the VRF under that VPN will get affected unless they are
explicitly configured with a value.
