HP Comware 5 Debug Manual Vol 3

Field
Description
Rtr Priority: rt-pri, Dead Int: dead-interval, DR: ip-addr
,
BDR: ip-addr
OSPF hello packet information:
• rt-pri—Router priority.
• dead-interval—Neighbor dead interval , in
seconds.
• ip-addr—IP address of the DR or BDR on the
interface network segment.
Attached Neighbor: rt-id
OSPF hello packet information.
rt-id indicates the router ID of the neighbor discovered
by OSPF.
Hello: hello timer mismatch
OSPF hello packet information.
Hello intervals of the router and the neighbor are
different.
Hello: dead timer mismatch
OSPF hello packet information.
Dead intervals of the router and the neighbor are
different.
Hello: netmask mismatch
OSPF hello packet information.
Network masks of the router and the neighbor are
different.
Hello: extern option mismatch
OSPF hello packet information.
The optional capability support of the router and that
of the neighbor are different.
Extended Options(LLS Data): opt
OSPF hello and DD packet information.
opt indicates the GR-related options:
• LR—OOB negotiation.
• RS—Notifying the neighbor to enter the GR
(Graceful Restart) state.
MTU:mtu-val, Option: opt, R_I_M_MS Bit: bits
OSPF DD packet information. This argument can be a
combination of the following values:
• mtu-val—MTU on the interface, in bytes. It is 0 if
the MTU of the DD packets is not configured as that
of the sending interface.
• opt—Optional capabilities supported by the
router:
 E bit means external route support.
 The "N" and "P" in N/P bit mean NSSA
capability and Type 7 to Type 5 translation,
respectively.
 L bit means the packet carries GR-related
extended data.
• bits—DD packet negotiation bit:
 I bit means the negotiation starts.
 M bit means more DD packets are to be
exchanged.
 MS bit means it is the master.
 R bit means OOB negotiation begins.
