After complete configuration of the site-site VPN, the following error would show up while running the command shown:
vyatta# run show vpn ipsec status
IPSec Process Running PID: 3300
1 Active IPsec Tunnels
IPsec Interfaces :
eth0 (no IP on interface statically configured as local-ip for any VPN peer)
After searching online, I came across the following community post that wasn’t of much help. Based on input from Brocade TAC Engineers, the above bug is superficial and doesn’t affect the functionality of the site-site IPSec tunnel configured on the Vyatta device. For now, this can be ignored as a benign bug.
