This commit adds a function that iterates over all IS-IS areas and asks the SRv6 Manager for information about the configured locators. Signed-off-by: Carmine Scarpitta <cscarpit@cisco.com> (cherry picked from commit 0b76fb3)
When SRv6 is enabled and an SRv6 locator is specified in the IS-IS configuration, IS-IS may attempt to request SRv6 locator information from zebra before the connection is fully established. If this occurs, the request fails with the following error: ``` 2025/02/14 21:41:20 ISIS: [HR66R-TWQYD][EC 100663302] srv6_manager_get_locator: invalid zclient socket ```` As a result, IS-IS is unable to obtain the locator information, preventing SRv6 from working. This commit fixes the issue by ensuring IS-IS requests SRv6 locator information once the connection with zebra is successfully established. Signed-off-by: Carmine Scarpitta <cscarpit@cisco.com> (cherry picked from commit f02dba1)
