VIP IP address stops working!!
We have an Aryaka VPN or SD-WAN setup. Which includes 2 Aryaka ANAP HA devices each one connected into our Core HP Switch 8212zl to the VLAN that is our gateway through our SonicWall NSA 5600 Firewall. We are also running VRRP along with BGP. The Aryaka has a Gateway IP 172.26.90.14 and 2 other IP addresses for the Ethernet cards 172.26.90.2 & 172.26.90.3. The HA setup requires a VIP IP address so we use 172.26.90.1 Subnet Mask /28…All has been working fine for years. But now we need to change the VIP IP address every 5 months because it becomes very slow with high Latency . Typically our QOS 50ms But the VIP is returning Pings as high as 600ms and dropped connections.
Ready for this ? When we change the VIP IP address to a different IP i.e. 172.26.90.4 everything returns to normal again for about 5 months and then we need to change it again!! Any Ideas why a VIP IP address becomes stagnant or broken??? Thanks in advance…
