ostate and nstate are Neighbor State Codes. The Neighbor State Codes are described in RFC 1583. See Related protocol specifications for information about accessing RFCs. The Neighbor State Codes can be one of the following:

1

Down

2

Attempt

4

Init

8

2-way

16

ExStart

32

Exchange

64

event is the Neighbor Event Code. The Neighbor Event Codes are described in RFC 1583. See Related protocol specifications for information about accessing RFCs. The Neighbor Event Codes can be one of the following:

7

SeqNumberMismatch

8

BadLSReq

10

1-way

11

KillNbr

12

InactivityTimer

13

LLDown

15

NoProg. This event is not described in RFC 1583. This is an indication that adjacency establishment with the neighbor failed to complete in a reasonable time period (Dead_Router_Interval seconds). Adjacency establishment restarts.

16

MaxAdj. This event is not described in RFC2328. This indicates that OMPROUTE has exceeded the futile neighbor state loop threshold (DR_Max_Adj_Attempt). Even if a redundant parallel interface (primary or backup) exists, OMPROUTE continues to attempt to establish adjacency with the same neighboring designated router over the existing or alternate interface.

See the network design considerations with z/OS® Communications Server information in z/OS Communications Server: IP Configuration Guide for more information about futile neighbor state loops.
