If I am using compressed header the RFC 2508 states that the layer2 protocol
should be able to provide indication for the following 4 packet formats:
1) FULL_HEADER
2) COMPRESSED_UDP
3) COMPRESSED_RTP
4) CONTEXT_STATE

If I am using ethernet for layer2, with type encapsulation
Can somebody help me in finding the type opcodes for incating the
above 4 conditions?Where can I get more information about it?

Thanks

RFC2508 does not take into account ethernet. Notice that it discusses low speed serial links.

When “requirements that the link layer provide some packet type codes, a packet length indication, and good error detection.”, I think the standard HDLC, Frame, and PPP types of encapsulation will take care of those “requirements.”

If you have a lot of bandwidth, such as ethernet, do you really need header compression?
