May I recommend a different approach instead?
Download and compile bgpq3:
git clone https://github.com/snar/bgpq3.git && cd bgpq3 && ./configure && make
Run bgpq3:
Vurt:~ job$ bgpq3 -6 -A -R 128 -l AS15562pfx AS15562
no ipv6 prefix-list AS15562pfx
ipv6 prefix-list AS15562pfx permit 2001:67c:208c::/48 le 128
ipv6 prefix-list AS15562pfx permit 2001:67c:2980::/48 le 128
ipv6 prefix-list AS15562pfx permit 2001:728:1808::/48 le 128

bgpq3 supports BIRD, IOS, XR, JunOS & JSON output. See bgpq3 -h for all
options
Kind regards,
