VIAVI TestCenter: Why few DHCPv6-PD sessions are not coming over PPPoE?
Issue:
• Configured 4 device blocks with 4000 PPPoE/DHCPv6-PD sessions.
• All the PPPoE sessions came up successfully; 12,613 DHCPv6-PD sessions bound and 3387 sessions failed.
• As a workaround, bringing down the DHCPv6-PD session followed by the PPPoE session and again restart both the protocols helped in bringing up all the DHCPv6-PD sessions.
Resolution:
• The 4 device blocks had same starting MAC address but were in different VLANs. Making the MAC address unique helped bring up all the DHCPv6-PD session.
