IP Address Displays the IP address of the virtual neighbor.
The router uses the IP address to send OSPF packets across the transit
network to the virtual neighbor.
Possible values:
Valid IPv4 address
Options Displays the information contained in the options field of the LSA. This value
indicates the capabilities of virtual neighbor.
The options field used in the hello packets allow routers to identify their
optional capabilities, and to communicate the capabilities to other routers.
This mechanism allows you to mix routers of different capabilities within a
routing domain.
The router supports 4 options by setting the following bits in the options field
either high or low depending on the capabilities of the router. The field
displays the value by adding the following option bits together. You read the
fields from least significant bit to most significant bit.
– The routers advertise the ability to process TOS 0 in AS external routes
when it sets the E-bit high. The E-bit is the second bit in the options field
and represents the value 2^1 or 2.
– The routers advertise the ability to process multicast routes when it sets
the MC-bit high. The MC-bit is the third bit in the options field and
represents the value 2^2 or 4.
– The routers advertise the ability to process AS external routes in an
NSSA summary with type 7 LSAs when it sets the N/P-bit high. The
N/P-bit is the fourth bit in the options field and represents the value 2^3
or 8.
– The routers advertise the ability to process demand circuits when it sets
the DC-bit high. The DC-bit is the sixth bit in the options field and
represents the value 2^5 or 32.
In a special case, the router sets the E-bit low.
– The routers advertise the ability to process TOS metrics other than TOS
0 when it sets the E-bit low. The E-bit is the second bit in the options
field and when set low, the bit represents the value 0.
Possible values:
2,6,10,14,34,38,42,46
The values indicate that the virtual neighbor supports Type of Service
metric (TOS) 0 in AS external LSAs.
0,4,8,12,32,36,40,44
The values indicate that the virtual neighbor supports TOS metrics other
than TOS 0.
4,6,12,14,36,38,44,46
The values indicate that the virtual neighbor supports multicast routing.
8,10,12,14,40,42,44,46
The values indicate that the virtual neighbor supports type 7 LSAs.
32,34,36,38,40,42,44,46
The values indicate that the virtual neighbor supports demand circuits.
