CR00023393 PPP 3 If the router or switch was acting as a PPPoE Access Concentrator, and it
was power-cycled or restarted, then re-establishing any existing PPPoE
sessions could take longer than necessary. This was because the router or
switch would send the incorrect PADT in response to PPPoE session packets
sent from the existing PPPoE session (EtherType of 0x8664, the PPPoE
Session Protocol). Some PPPoE clients would ignore this PADT, causing a
delay before the PPPoE session was re-established.
This issue has been resolved. The router or switch now send the correct
PADT in response to any existing sessions after restarting (EtherType of
0x8663, the PPPoE Discovery Protocol).

CR00024495 OSPF 3 Previously, if a new OSPF router ID was learned via an OSPF point-to-point
(PTP) link, the original OSPF router ID was not removed from the show
ospf neighbour command output.
For PTP networks, incoming OSPF hello packets are used to update
neighbour information. On an PTP interface, existing neighbours are
matched by the router ID in the hello packet, whereas on other types of
interfaces the neighbours are matched by source address.
In the case of a PTP network, however, there are only ever 2 ends to the
network and so there should only be one existing neighbour for the
interface.
This issue has been resolved. Now, if a new OSPF Router ID is learned via an
OSPF PTP link, the original OSPF Router ID is removed from the show ospf
neighbour command output.
