what is the diffrence between ospf and ospfv3?
can anyone help me with this information
It’s for use with IPv6. From newsletter #11:
OSPF version 3 support has been added in RouterOS 3.12 (using routing-test package). OSPFv3, specified in RFC 2740, is the protocol’s version for IPv6 routing.
OSPFv3 uses the same fundamental mechanisms as OSPFv2 — LSAs, flooding, the SPF algorithm, etc. However, it’s not only an extension of OSPFv2 for new
address family, but also a new improved version of the protocol itself. OSPF was designed in the late 1980 when requirements for routers were very different from today’s. OSPFv3 brings the protocol more up to date, as well as avoids some inefficiencies discovered in operation of OSPFv2.
OSPFv3 configuration syntax largerly remains the same (it’s accessible in CLI under /routing ospf-v3). One major difference is that there is no configuration for networks anymore, and interface configuration becomes
manadatory.
thanks for the reply
where are ospfV3 routing filters? I no longer see any reference to routing-filters, and ospf-in and ospf-out aren’t there by default. Please help someone trying to figure out which routing protocol to use to redistribute ipv4 and ipv6 without multiple routing protocols running : )
Also, the default OSPFv3 instance somehow ends up with invalid numbers and can’t be saved without fixing it:
When you make a change and hit submit it complains about the numbers above.
