On the OS6600 series, OSPF ECMP gateways are not correctly computed when there is more than one
point-to-point or point-to-multipoint interface between a pair of OSPF routers.
Workaround: There is no known workaround at this time.

Problem Reports
PR 73783
On an OS7000 series switch, a lot of register packets will stress the NI. Everything is going through software and so the NI will be very busy.
Workaround: There is no known workaround at this time.
PR 74581
Some releases of Cisco's PIM implementation default to "full packet" checksums for their register packet
checksum algorithm. This causes Cisco routers to reject valid PIM register packets from an OS7000 PIM
implementation, which defaults to "header only" checksums for PIM register packets.
Workaround: Change “register checksum” to “full” when connecting Cisco PIM-SM router to the
OS7000 series switch.
PR 74719
If a Cisco router is configured as a C-BSR with the highest priority and it is not directly connected to the
OS7000s, the OS7000s will not see the Cisco router as the BSR.
Workaround: Configure the OS7000 to be the BSR instead of the Cisco router if the Cisco router is not
directly connected to the OS7000.
PR 74815
On an OS7000 series switch, the hashing function, which calculates the hash value used to map a group to
an RP, has problems when running with a Cisco router. It appears that the Cisco box is forgetting the last
part of the formula (mod 2^31) which masks off the upper bit.
Workaround: When running PIM-SM with a Cisco router, do not use multiple RPs with the same priority.
