Static Routing

Command Description
ipv6 route ipv6-prefix/prefix-length

{ipv6-address | interface-type interface-number

[ipv6-address]} [administrative-distance]

[administrative-multicast-distance | unicast |

multicast] [tag tag]


Example:

Router(config)# ipv6 route ::/0 serial 2/0

Configures a static IPv6 route
  • A static default IPv6 route is being configured on a

serial interface.

  • See the syntax examples that immediately follow this

table for specific uses of the ipv6 route command for

configuring static routes.

Summary Steps

  1. enable
  2. configure terminal
  3. ipv6 route ipv6-prefix/prefix-length {ipv6-address | interface-type interface-number

[ipv6-address]} [administrative-distance] [administrative-multicast-distance | unicast | multicast] [tag tag]

RIPng

Command Description
ipv6 unicast-routing


Example: Router(config)# ipv6 unicast-routing

Enables the forwarding of IPv6 unicast datagrams
ipv6 rip name enable


Example: Router(config-if)# ipv6 rip process1 enable

Enables the specified IPv6 RIP routing process on an

interface

maximum-paths number-paths


Example: Router(config-router)# maximum-paths 1

(Optional) Defines the maximum number of equal-cost

routes that IPv6 RIP can support

  • The number-paths argument is an integer from 1 to 64.

The default for RIP is four paths.

ipv6 router rip word


Example: Router(config)# ipv6 router rip process1

Configures an IPv6 RIP routing process and enters router

configuration mode for the IPv6 RIP routing process.

  • Use the word argument to identify a specific IPv6 RIP

routing process

ipv6 rip name default-information {only \

originate} [metric metric-value]


Example: Router(config-if)# ipv6 rip process1 default-information originate

(Optional) Originates the IPv6 default route (::/0) into the

specified RIP routing process updates sent out of the specified interface.

Summary Steps

  1. enable
  2. configure terminal
  3. ipv6 router rip word
  4. maximum-paths number-paths
  5. exit
  6. interface type number
  7. ipv6 rip name default-information {only | originate} [metric metric-value]

IS-IS

Command Description
router isis area-tag

Example: Router(config)# router isis area2

Enables IS-IS for the specified IS-IS routing process, and

enters router configuration mode.

net network-entity-title

Example: Router(config-router)# net 49.0001.0000.0000.000c.00

Configures an IS-IS network entity title (NET) for the

routing process.

ipv6 router isis area-name

Example: Router(config-if)# ipv6 router isis area2

Enables the specified IPv6 IS-IS routing process on an

interface. configuration mode


OSPFv3

Command Description
router ospfv3 [process-id]

Example: Router(config)# router ospfv3 1

Enables OSPFv3 router configuration mode for the IPv4 or

IPv6 address family.

nssa | stub]

Example: Router(config-router)# area 1

Configures the OSPFv3 area.
auto-cost reference-bandwidth Mbps

Example: Router(config-router)# auto-cost reference-bandwidth 1000

Controls the reference value OSPFv3 uses when calculating

metrics for interfaces in an IPv4 OSPFv3 process.

bfd all-interfaces

Example: Router(config-router)# bfd all-interfaces

Enables BFD for an OSPFv3 routing process

virtual-link router-id]} [default-information originate [always | metric | metric-type | route-map] | distance | distribute-list prefix-list prefix-list-name {in | out} [interface] | maximum-paths paths | redistribute protocol | summary-prefix ipv6-prefix]

Example: Router(config-router)# default area 1

Returns an OSPFv3 parameter to its default value.
ignore lsa mospf

Example: Router(config-router)# ignore lsa mospf

Suppresses the sending of syslog messages when the router

receives LSA Type 6 multicast OSPFv3 packets, which are unsupported.

interface-id snmp-if-index

Example: Router(config-router)# interface-id snmp-if-index

Configures OSPFv3 interfaces with Simple Network

Management Protocol (SNMP) MIB-II interface Index (ifIndex) identification numbers in IPv4 and IPv6.

log-adjacency-changes [detail]

Example: Router(config-router)# log-adjacency-changes

Configures the router to send a syslog message when an

OSPFv3 neighbor goes up or down.

passive-interface [default interface-type

interface-number]

Example: Router(config-router)# passive-interface default

Suppresses sending routing updates on an interface when

using an IPv4 OSPFv3 process.

queue-depth {hello update} {queue-size

unlimited}

Example: Router(config-router)# queue-depth update 1500

Configures the number of incoming packets that the IPv4

OSPFv3 process can keep in its queue.

router-id {router-id}

Example: Router(config-router)# router-id 10.1.1.1

Use a fixed router ID.

Summary Steps:

  1. . enable
  2. . configure terminal
  3. . router ospfv3 [process-id]
  4. . address-family ipv6 unicast
  5. . area area-ID range ipv6-prefix/prefix-length
  6. . default {area area-ID [range ipv6-prefix | virtual-link router-id]} [default-information originate

[always | metric | metric-type | route-map] | distance | distribute-list prefix-list prefix-list-name {in | out} [interface] | maximum-paths paths | redistribute protocol | summary-prefix ipv6-prefix]

8. default-metric metric-value

9. distance distance

ipv6 router eigrp as-number


Example: Router(config-if)# ipv6 router eigrp 1

Enters router configuration mode and creates an EIGRP

IPv6 routing process

show ipv6 eigrp [as-number] interfaces [type

number] [detail]


Example: Router# show ipv6 eigrp interfaces

Displays information about interfaces configured for

EIGRP for IPv6.

Summary Steps

  1. enable
  2. configure terminal
  3. ipv6 unicast-routing
  4. interface type number
  5. no shut
  6. ipv6 enable
  7. ipv6 eigrp as-number
