Step Description Command Keys
27 Specify the list of passwords for
authentication via md5 hashing
algorithm.
esr(config-ospf- vlink)#
authentication key chain
<KEYCHAIN>
<KEYCHAIN> – key list
identifier, set by the string of up
to 16 characters.
28 Enable virtual connection. esr(config-ospf- vlink)# enable
29 Switch to the interface/tunnel/network
bridge configuration mode.
esr(config)# interface <IF-
TYPE><IF-NUM>
<IF-TYPE> – interface type;
<IF-NUM> – F/S/P – F frame
(1), S – slot (0), P – port.
esr(config)# tunnel <TUN-
TYPE><TUN-NUM>
<TUN-TYPE> – tunnel type;
<TUN-NUM> – tunnel number.
esr(config)# bridge <BR-NUM> <BR-NUM> – bridge number.
30 Define the interface / tunnel / network
bridge inherence to a specific OSPF
process.
esr(config-if-gi)# ip ospf instance
<ID>
<ID> – process number, takes
values of [1..65535].
esr(config-if-gi)# ipv6 ospf
instance <ID>
31 Define the interface inherence to a
specific OSPF process area.
esr(config-if-gi)# ip ospf area
<AREA_ID>
<AREA_ID> – area identifier,
defined as AAA.BBB.CCC.DDD
where each part takes values
of [0..255].
esr(config-if-gi)# ipv6 ospf area
<AREA_ID>
32 Enable the routing via OSFP on the
interface.
esr(config-if-gi)# ip ospf
esr(config-if-gi)# ipv6 ospf
33 Enable the mode in which the OSPF
process will ignore MTU interface value
in incoming Database Description
packets.
esr(config-if-gi)# ip ospf mtu-
ignore
esr(config-if-gi)# ipv6 ospf mtu-
ignore
