All Cisco-Network Study Notes: Configuring Multicast Acquisition for IPv6

Configuring Multicast Acquisition for IPv6

The aboriginal footfall in configuring multicast on a Cisco IOS router or about-face is to accredit multicast

routing:

Jeter(config)# ipv6 multicast-routing

Once multicast acquisition is enabled, you can configure PIM on the adapted interfaces, acclimatize MLD

configuration, and accredit any added all-important appearance such as BSR, MLD, and so forth. Cisco IOS

IPv6 multicast agreement is so agnate to IPv4 that its advantage ends here; accredit to Affiliate 17

for added details.

This breadth lists added capacity and facts to annular out the advantage of the capacity in this chapter.

Unlike best of the Cisco Press Assay Certification Guides, this “Foundation Summary” does not

repeat advice presented in the “Foundation Topics” breadth of the chapter. Please booty the

time to apprehend and abstraction the capacity in the “Foundation Topics” breadth of the chapter, as able-bodied as

review items acclaimed with a Key Topic icon.

Table 20-9 Command Advertence for Affiliate 20

Command Description

[no] ipv6 unicast-routing Globally enables or disables IPv6 acquisition functionality.

show ipv6 interface {type number} Displays agreement of all IPv6 interfaces or a

selected interface, if defined in {type number},

including all-around unicast and link-local address, MTU,

and added parameters.

show ipv6 interface abrupt Displays a arbitrary of IPv6 interfaces.

ipv6 abode {ipv6-address/prefixlength

| prefix-name sub-bits/prefixlength

| autoconfig} {anycast | eui-64 |

link-local}

Configures a all-around unicast (EUI-64 or non-EUI-64),

link-local, or anycast abode on an IPv6 interface.

[no] ipv6 avenue {destination-prefix}

{next-hop-ipv6-address | outgoinginterface}

{next-hop-ipv6-address |

administrative-distance | multicast | tag

| unicast}

Creates a changeless avenue to a prefix allegorical an IPv6

address or interface, or both, as the abutting hop. Optionally

configures authoritative ambit and avenue tag and

qualifies this changeless avenue to be acclimated for alone multicast or

for alone unicast routing.

ipv6 multicast-routing Enables IPv6 multicast globally.

ipv6 mld Interface command for configuring Multicast Listener

Discovery options.

ipv6 pim Enables PIM on an IPv6 interface.

ipv6 ospf process-ID breadth area-ID Activates OSPFv3 on an interface and sets the

interface’s OSPF area.

The CCIE Acquisition and Switching accounting exam, like all Cisco CCIE accounting exams, covers a fairly

broad set of topics. This breadth provides some basal accoutrement to advice you exercise your anamnesis about
