ASR l2tp session limitation

Hello,

Are there any limitations on ASR1002 for l2tp session? My ASR can't terminate more than 4023-4030 session.

Re: ASR l2tp session limitation

Yes - there are different types of session (ppp or l2tp) limitation based on the combination of what kind of RP (RP1 vs RP2) or/and ESP types.

for ASR1002 with RP1 and 5-Gbps ESP module should be able to support - 12,000 ppp sessions and 6,000 Layer 2 Tunneling Protocol (L2TP) tunnels

hope this help
