Symptom: When sub-interfaces are configured with IPv6 addresses having the same subnet mask but with different network addresses, only one of those addresses gets correctly configured. Example: 2001:10::1/119 and 2001:10::201/119 Here, both the IPv6 addresses have a subnet mask of 119. Meaning, the last 9 bits reserved for hosts. But their initial 119 bits of prefix differs. Conditions: Multiple sub-interfaces configured with the same subnet mask. Example: 2001:10::1/119 and 2001:10::201/119 2001:10::1/118 and 2001:10::401/118
