Wrong BGP next hop programming

$

Hi,

 

Please consider below topology:

 

DLR1(AS65001)             --->           ESG1(AS65001)        ------------------------------> Physical Router(AS65002)

192.168.1.1/30                    192.168.1.2/30                      192.168.100.3/24            192.168.100.1/24

 

- Static route 172.16.0.0/19 is configured on DLR1 and redistributed via BGP to ESG1

- ESG1 advertises stiatic route 172.16.0.0/29 to Physical Router

 

- static route 172.16.0.0/19 is advertised from ESG1 to Physical router with 192.168.1.1 as Next Hop which is wrong and Physical router didn't install the static route

 

I believe the Next Hop attribute programming is incorrect when ESG1 advertise the route to physical router, NEXT Hop must be 192.168.100.3 instead of physical Router IP address (ie 192.168.1.1)

 

Please find attached output from ESG, the output includes:

- Routes advertised to Physical router 192.168.100.1

- Routes received from DLR1 : 192.168.1.1

- directly connected routes on ESG1

 

Best Regards
