EZZ7919I State change, ipversion OSPF, neighbor neighbor, new state state, event event
Explanation
The specified event was generated, causing the specified neighbor to transition to the specified new state.
ipversion is
the IP version that OSPF is running. Possible values for ipversion are:
- IPv6 — OSPF for IPv6
- IPv4 — OSPF for IPv4
neighbor is the neighboring OSPF router. If ipversion is IPv4, it is the neighbor's interface address on the common network. If ipversion is IPv6, it is the neighbor's OSPF router ID.
state is
the Neighbor State Code. The Neighbor State Codes are described in
RFC 2328. See Related protocol specifications for directions to
get a copy of the RFC. The Neighbor State Codes can be one of the
following:
- 1
- Down
- 2
- Attempt
- 4
- Init
- 8
- 2-way
- 16
- ExStart
- 32
- Exchange
- 64
- Loading
- 128

event is the Neighbor Event
Code. The Neighbor Event Codes are described in RFC 2328. See Related protocol specifications for directions to get a copy of the RFC.
The Neighbor Event Codes can be one of the following:
- 1
- HelloReceived
- 2
- Start
- 3
- 2-WayReceived
- 4
- AdjOK?
- 5
- NegotiationDone
- 6
- ExchangeDone
- 7
- SeqNumberMismatch
- 8
- BadLSReq
- 9
- LoadingDone
- 10
- 1-way
- 11
- KillNbr
- 12
- InactivityTimer
- 13
- LLDown
- 14
- AdjStart. This event is not described in RFC2328. Bidirectional communication was established with the neighbor and this is a neighbor with whom an adjacency should be established.
- 15
- NoProg. This event is nott described in RFC2328. 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.
