Viewing IPv4 and IPv6 Addresses
Viewing IPv4 and IPv6 Addresses
Cisco ANA transparently handles IPv4 and IPv6 addresses within the limitations described in the “Cisco
ANA 6VPE Support Limitations” section on page 6-5. Cisco ANA NetworkVision displays IPv6
addresses when they are configured on PE and CE routers in the Cisco ANA NetworkVision IP interface
table. The IP interface table appears in the following locations:
• Port inventory view—IPv6 addresses appear under the Sub Interfaces tab in the interface table and
interface properties popup window.
• VRF inventory view—IPv6 addresses appear under the Sites tab in the interface table and interface
properties popup window.
• Routing entity view—IPv6 addresses appear under the IP Interfaces tab in the table view when
applicable, and the interface properties popup window.
The IP addresses that appear depend on whether the interface has only IPv4 addresses, only IPv6
addresses, or both IPv4 and IPv6 addresses, as shown in Table 6-1.
Note To display the properties window, right-click the IP address in the interface table and choose Properties.
Figure 6-2 shows a port inventory view of a Cisco CRS-1 Carrier Routing System port with IPv4 and
IPv6 addresses. In this example, one IPv4 address and multiple IPv6 addresses are provisioned on the
interface.
• The primary IPv4 address appears in the interface table and properties window. If secondary IPv4
addresses were provisioned on the interface, they would appear in the properties window.
• IPv6 addresses provisioned on the interface appear only in the properties window.
