Cisco Cisco IOS XR Software Release 3.2

The following caveats apply to all platforms:

Brief Description: Internally found cosmetic defect: Assigned (A) % complete during the install 
add command is inaccurate.

Symptoms: During the install add command operations, there may be a window of 4-5 minutes in 
which no add operation status is displayed on the user’s terminal or console. 

Conditions: This occurs only when performing the install add command operations. 

Workaroud: No workaround. Note that this does not impact the add operation. The user should wait 
for the next install % (percentage) message to see the status of the install add command operations. 

Basic Description: IPv6 ping fails to link-local address. 

Symptom: An error "ping6: failed to get receiving hop limit" is displayed and IPv6 ping to a directly 
connected neighbor's link-local address is not successful. IPv6 ping to the interface is successful.

Conditions: This symptom occurs on Cisco routers with 3.2.2 Cisco IOS XR software configured 
with IPv6.

Workaround: No workarounds.

Basic Description: Removing and restoring configuration of address family can cause a BGP peer 
to remain down. 

Symptom: IPv4 BGP neighbors do not come up after Address Family Identifier configuration is 
restored. 

Conditions: If the address-family ipv4 is restored (for example, with rollback configuration) under 
router BGP approximately three minutes after the configuration was removed, the IPv4 BGP 
neighbors do not come back up.

Workaround: Restart the bgp process on the RP by using process restart bgp command. 

Basic Description: An Optical User Network Interface (OUNI) connection goes down a few 
minutes after the Resource Reservation Protocol (RSVP) hellos come back up. 

Symptom: On an RSVP hello control-channel failure, an OUNI connection may go down. 

Conditions: The OUNI connection goes down if the control channel failure is detected by the 
passive side of the OUNI connection. This is because the passive side of the OUNI connection stops 
refreshing its RSVP state for the OUNI connection, and the active side eventually times out.

Workaround: After the RSVP hello control-channel failure on the passive side restart the RSVP 
process with process restart rsvp command.

The following caveats are specific to the Cisco CRS-1 platform:

Basic Description: On Cisco CRS-1 single-shelf chassis, the show hfr command shows 
UNKNOWN entry after multiple AM0/AM1 card OIRs.
