OSPFv3 and RIPng

Sun Feb 21, 2021 1:18 am

According to https://help.mikrotik.com/docs/display/ ... col+Status

RIP and OSPF should be functional under 7.1beta4.

However, I've tested on RB3011, CRS309, and CCR1009, with fiber, copper, and DAC at 1 and 10G, and have suffered abject failure.

OSPFv3 results in the following in the log:
OspfInterface { { *2 0.0.0.0 0 0.0.0.0 } Point-to-Point PtP-unnumbered } wrong checksum from fe80::4a8f:5aff:fec9:cea1%*2

and similarly for broadcast interface type, etc.

RIP with AFI IPv6 gives the following error for any configured interfaces:
"interface has no IPv6 link local address" despite there palpably being dynamic link local addresses in the IPv6 address list. Is this a VRF failure?

Any advice welcome.

Yup, I get wrong checksum for everything too. Haven't found a solution yet.

Also reporting checksum errors for OSPFv3 hello packets received by ROS v7.1beta5. Wireshark says the checksum that ROS v6.48.2 is putting out in the OSPFv3 hello packet is correct, but ROS v7.1beta5 is logging OspfInterface { { *1 0.0.0.0 0 0.0.0.0 } DR Broadcast } wrong checksum from <LL IPv6 address of ROS6 interface>%*1 for every hello received. ROS6 lists the ROS7 box as a neighbor in the state: init, and logs no errors. The ROS7 box does not list the ROS6 box as an OSPFv3 neighbor.

OSPFv2 is working fine so far. States are full and routes are passing across.

ROS6 box: RB750UP
ROS7 box: RB493AH
