Good morning (afternoon) all,

Have the following question in regards to a tunnel I'm trying to established between a Netscreen and a 3845:

#sh ver
Cisco IOS Software, 3800 Software (C3845-ADVIPSERVICESK9-M), Version 12.4(6)T1, RELEASE SOFTWARE (fc3)
...

ROM: Cisco IOS Software, 3800 Software (C3845-IPBASE-M), Version 12.3(11)T5, RELEASE SOFTWARE (fc1)


My network information:

My VPN Peer address:
10.10.53.98

My ACL Host range:
10.10.53.192/30

Client's Netscreen Peer address:
10.15.179.238

---
Their networks:

Customer Pre-shared key:
secret

PHASE 1 proposal:    DH group2-3des-md5
PHASE 2 proposal:    PFS group2-esp-3des-md5

Client's ACL host range:
10.10.178.192/30



My configs:

crypto isakmp policy 10
encr 3des
hash md5
authentication pre-share
group 2
lifetime 28800
crypto isakmp key secret address 10.15.179.238

crypto ipsec transform-set predefined esp-3des esp-md5-hmac

crypto map defined 10 ipsec-isakmp
set peer 10.15.179.238
set transform-set predefined
set pfs group2
match address 112

access-list 112 permit ip 208.50.53.98 0.0.0.7 63.79.178.192 0.0.0.3

Question... Since I have a constant 20+Mpbs on one of my interfaces, I'm reluctant to have an outage...

interface Serial1/0.xxx point-to-point
description xxx.xxx.xxx.xxx
ip address 10.5.5.106 255.255.255.252
frame-relay interface-dlci xxx

If I apply the crypto map predefined to this interface, would it drop all traffic non encrypted?

interface Serial1/0.xxx point-to-point
description xxx.xxx.xxx.xxx
ip address 10.5.5.106 255.255.255.252
frame-relay interface-dlci xxx
crypto map predefined
