Description (partial)

Symptom:
ASR1K acting as an IKEv2 VPN server experiences an address pool leak when we have local address pools configured with the group parameter. The issue is seen upon AnyConnect auto-reconnect and subsequent disconnect (the disconnect being a graceful one).

Conditions:
Issue first found on ASR1K running 3.13 and 3.14 codes. The important thing is the group parameter in the address pool being used. The format of this is:

ip local pool pool1 x.x.x.x y.y.y.y group V1
