Headline: MPLS Labels not being advertised to neighbor switches after reboot on Nexus 9336C.

Symptoms: Network topology configured with Segment Routing + MPLS network for L3VPNS on 4 X Nexus 9336C switches (NX-OS mode). OSPF as the IGP and to advertise the MPLS labels. Labels are learnt once its configured. Once any one of the Nexus devices are rebooted, the label from the switch is no longer advertised by the switch that was rebooted to any other neighbor Nexus devices. The same occurs for any switch that is rebooted. OSPF database opaque external type 7 prefix is not generated or advertised to other neighbor switches by the switch which was rebooted.

Workarounds: When a command is entered under the Segment Routing configuration section. For example: global block range or a prefix, something triggers the labels to be advertised via OSPF and the type 7 prefix is visible in the OSPF database and subsequently installed in the MPLS forwarding table of the remaining three switches. Workaround: Remove p2p config from loopback interface.

Headline: Smart licensing - Callhome HTTP proxy does not work when it is defined using IPv6 address.

Symptoms: Communications with CSSM portal do not work when using IPv6 HTTP proxyDevice reports:

%LICMGR-3-LOG_SMART_LIC_COMM_FAILED: (pid=xxxx) Communications failure with the Cisco Smart Software Manager (CSSM): Fail to send out Call Home HTTP message

Workarounds: Instead of referencing the HTTP proxy using IPv6, use HOSTNAME and define static IPv6 host config. For example,

Instead of:

***********

callhome

...

  transport http proxy server X:X::X:X port 8080

***********

use:

***********

ipv6 host test.proxy.com X:X::X:X

callhome

...

  transport http proxy server test.proxy.com port 8080
