Adding the dotted notation will fail as seen below.
FGT # config router bgp
FGT (bgp) # set as
as <----- Enter an integer value from <0> to <4294967295>.
FGT (bgp) # set as 65001.65001
invalid integer value: .65001
value parse error before '65001.65001'
Command fail. Return code -1
Solution
To add 4 bytes AS numbers, the dotted notation has to be converted to decimal notation to be added to the config.
+ Can be converted in the APNIC converter tool , https://submit.apnic.net/cgi-bin/convert-asn.pl
+ '65001.65001' is Converted to ASN: 4259970537.
FGT # config router bgp
FGT (bgp) # set as 4259970537
FGT (bgp) # show
# config router bgp
(bgp) # set as 4259970537
