Affected Product(s):
BIG_IP_NEXT(SPK) SPK
Fixed In:
1.7.2
Opened: Apr 19, 2023 Severity: 3-Major
A small subnet (8 IP addresses for example), will always return a sorry IP
Client egress traffic will always be directed towards the sorry IP.
- Configured F5SPKEgress with a small dnsNat46Ipv4Subnet (eg. 8ips), where the number of (tmm pods * allocated cpus per pod) is less than (subnet ip count / 2).
Increase the size of dnsNat46Ipv4Subnet, or reduce the number of total allocated cpus (less pods, or less allocated cpus per pod)
Small subnets now work as expected, as long each cpu can allocate at least 1 IP; a cpu cannot have 0 allocated IPs.
