When SRv6 is enabled and an SRv6 locator is specified in the BGP configuration, BGP 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: ``` 2025/02/06 16:37:32 BGP: [HR66R-TWQYD][EC 100663302] srv6_manager_get_locator: invalid zclient socket ```` As a result, BGP is unable to obtain the locator information, preventing SRv6 VPN from working. This commit fixes the issue by ensuring BGP requests SRv6 locator information once the connection with zebra is successfully established.
