eBGP Metric

Something does not make sense (I must be missing something).

BB1 and R9 are on AS1. R9 is receiveing Metric from iBGP peer.(10.10.10.11 is BB1).

r9#sb

   Network Next Hop Metric LocPrf Weight Path
*>i210.1.2.0 10.10.10.11 100 100 0 i
*>i210.2.2.0 10.10.10.11 100 100 0 i
*>i210.3.2.0 10.10.10.11 100 100 0 i
*>i210.4.2.0 10.10.10.11 100 100 0 i
*>i210.5.2.0 10.10.10.11 100 100 0 i
r9#

Debug on R9 shows it is sending the Metric to its eBGP peer R6.

*Mar 1 05:23:23.354: BGP(0): 150.100.3.6 send UPDATE (format) 210.1.2.0/24, next 150.100.3.254, metric 100, path
 
But output from R6 shows it is not present on show ip bgp on routers received from R9.
